CATARRH
Catarrh is the medical term for build up of mucus in the back of the nose, throat or sinuses. Doctors sometimes refer to catarrh as postnasal drip.
Often catarrh is the result of an intermittent or temporary illness, such as allergy or cold. It typically goes away once the illness has passed.
However, some people may experience *chronic* *catarrh* that persists for months or even years. It's not usually a cause for concern, but it can be a nuisance to live with.
A person with catarrh may feel the need to clear their throat frequently.
Mucus is a slipper, fluid substance that the mucus glands in the nose and throat produce. It helps moisten the nasal passages while trapping any debris, viruses or bacteria a person inhales. This helps prevent pathogens from getting into the body, where they could cause infection.
The body makes 1--2 quarts of mucus every day.
After production, the mucus drips down the back of the nose ND into the throat.
Usually people swallow the mucus without thinking about it. However, sometimes, the mucus can build up in the nose, throat or sinuses.
*SYMPTOMS*
Some symptoms of Catarrh include;
✍️ A tickling feeling of mucus draining into the throat rasping or gurgling when talking.
✍️ Feeling as though there is a lump in the throat having to clear the throat frequently.
✍️ Coughing and difficulty in swallowing
✍️ Sore throat
✍️ Blocked or stuffy nose.
✍️ Headache, loss of taste or smell and difficulty in sleeping.
*CAUSES* *OF* *CATARRH*
✍️Changes in weather conditions.
✍️ Eating Spicy foods.
✍️ High fever or allergic rhinitis nonallergic rhinitis viruses, such as the common cold sinus infection and nasal polyps.
✍️ Gastroesophageal reflux(GER).
✍️ Hormone changes during pregnancy.
✍️ Certain medications in children, having something stuck in the nose is a common cause of catarrh.
*When to see a Doctor*
A person should visit their doctor if they experience chronic catarrh that has persisted for several months or more, or if they find that catarrh is interfering with their everyday.
People also seek medical help if catarrh is accompanied by any of the following symptoms;
An unexplained high fever wheezing, shortness of breath blood in the mucus, foul-smelling. Mucus.
*Treatment*
Catarrh is a symptom with an underlying cause and it's typically harmless.
However, a person may seek treatment for the cause of persistent catarrh that is associated with pain, discomfort or irritation.
Over the counter (OTC) Treatment for catarrh include;
✍️ Nasal irrigation Oral decongestants, such as pseudoephedrine (Sudafed).
✍️ Mucus thinning medication such as guaifenesin( Mucinex) antihistamines to treat allergic causes of catarrh.
✍️ Pain relievers such as Acetaminophen or ibuprofen, to help ease headaches.
*Home Treatment also includes;*
✍️ Drinking plenty of water using an indoor humidifier inhaling the steam during a hot shower.
✍️ Gargling with warm salt water.
✍️ Using a saltwater solution to clean the insides of the nostrils.
✍️ Sleeping on propped up pillows.

WHY do people talk in their sleep?
Sleep talking is a common sleep disorder and, according to some researchers, occurs in 50% of young children. Sleep talking in adults occurs in about 5% of cases.
Dreaming is more common in people who are excitable and have experienced strong impressions, both positive and negative, on the previous day.
Still dreaming and dreaming are different things. A dream may be fantastic, unreal. Dreaming, as a rule, reflects real events experienced by a person.

WHY does beer make the belly grow?
The consequences of drinking beer are negative for men. When drinking this heady drink frequently, the content of estrogen (the female hormone) in the male body increases.
It contributes to the accumulation of excess blubber, which results in the formation of the so-called "beer belly".
It also leads to a serious hormonal failure, which spoils the figure and worsens men's @health.

The skin has only four colors
Without pigment, the skin is creamy white. Blood vessels that run near the surface give it a reddish blush.
In addition, there is a yellow pigment in the skin of any color. The last shade is the tone of melanin, which protects the body from UV rays.
In the end, the skin color of every person on the planet depends on the proportions in which these four shades are combined.

WHY does motion sickness occur?
It is caused by a malfunction of the vestibular apparatus, responsible for keeping us firmly on feet.
It reacts to changes in the position of the head and body in space, as well as to acceleration.
When a person's body moves and sways in a car or on a boat, the brain receives conflicting information from the different senses, which causes nausea, dizziness, and headaches.

What is Situs Inversus?
Situs inversus is a condition in which the organs of the chest and abdomen are arranged in a perfect mirror image reversal of the normal positioning.
Normal human development results in an asymmetrical arrangement of the organs within the chest and abdomen. Typically, the heart and spleen lies on the left side of the body (levocardia), the liver liver is located on the right, and the lung on the left has two lobes while the lung on the right has three lobes. This normal arrangement is known as situs solitus.
However, in about 1 in 8,500 people, the organs of the chest and abdomen are arranged in the exact opposite position: the heart is on the right (dextrocardia), as is the two-lobed lung, and the liver, spleen, and three-lobed lung are on the left. Yet because this arrangement, called situs inversus, is a perfect mirror image, the relationship between the organs is not changed, so functional problems rarely occur.

WHY can't people breathe and swallow at the same time?
The complex structure of the adult vocal apparatus does not allow humans, unlike animals, to breathe and swallow at the same time.
❗️Behind the root of the tongue is the supraglottic cartilage (epiglottis). It closes the entrance to the larynx when a food lump is swallowed, then opens to allow air to pass into the larynx and then through the respiratory tract.

WHY is the temperature on the thermometer set at 42° C?
Thermometer.jpg
Have you ever boiled an egg? After a few minutes of boiling, the protein curdles, becomes dense and white; this process is called denaturation.
At 42°C, the body also starts denaturing (clotting) blood proteins.
Furthermore, at this temperature, metabolic disorders begin in the brain. Such a condition is already incompatible with life, i.e. fatal.
One quarter of all your bones are located in your feet.
There are 26 bones in each foot. That's 52 bones in both feet, out of 206 total bones in your whole body, which is more than 25 percent. It may sound crazy at first, but think about it: Your feet support your weight and allow you to jump, run, and climb. Those bones and joints also allow your feet to absorb and release energy efficiently. It's one of the reasons humans can outrun any other animal in an endurance race.

��What is the meaning of Rx, Nrx and XRx printed on medicine packs
This is related to pharmacology and pharmacy.
Generally, in a prescriptions written by doctors have these symbols at the beginning.
• Rx-
◦ It actually comes from the word 'Recipere', meaning prepare.
◦ In medieval times, pharmacists used to make drugs and doctors would just write down the components and amounts to be needed and send the patients to the pharmacists with the prescription. The pharmacist would then prepare the drug as per doctor's instruction and give it to the patient with proper drug regimen.
◦ Now, pharamcists do not prepare drugs, rather dispense them. So Rx signifies the drugs in schedule H & H1 non-narcotic drugs, that means the can only be obtained by producing a prescription and not over-the-counter.
• NRx-
◦ The extra N prefix means the drug in the prescription has narcotic properties and are addictive.
◦ This also means that the prescription needs to be filled and signed every time by a doctor and the drug cannot be obtained if the prescription doesn't contain a recent date.
• XRx-
◦ This means the prescription contains a Narcotic and Psychotropic drug.
◦ So the drug retailer has to save a copy of the prescription for 2 years and has to produce the them on any enquiry on court order.
Nowadays these are not commonly used. Doctors usually write 'Adv' means 'Advice' and then write the drugs. It's the duty of the pharmacist to determine what drug is given and document it for future legal evidences.

How the kidneys work?
Kidney.mp4
The kidneys absorb and distribute 99.9% of the blood volume. Only 0.1% of filtered blood turns into urine.
To help your kidneys better excrete metabolic products, drink more pure water! No detox tea will help you as much as plain pure WATER.
��Why do doctors use Veins rather than Arteries to take blood samples?
Doctors can and do use arterial blood sampling but usually only when it is absolutely necessary ie. they need an arterial blood sample for arterial blood gas analysis (ABG) to find out how much oxygen and CO2 is in the arterial blood or when they cannot get venous access (for examples in trauma or otherwise seriously ill patients).
Venous blood is preferred for number of reasons:
- It is easier. Veins are superficial and there are lot of them. If you compress the arm proximally you can see and feel the veins running across the length of the upper limb. If you are taking arterial blood you usually go for the radial artery and you usually have to rely on the pulse you feel (or hear using doppler). Veins also tend to be more tethered if you pick the right spot ie the vein doesn't wiggle away when you try inserting the needle and you don't need to go fishing for it. Veins also have thinner walls which makes it easier to get a needle in. Novices (like myself) may need to use a bit more force to get into the artery and sometimes they push the needle right through the back wall in the process.
- Arterial blood samples are more painful for the patient. I haven't had one done on myself but I have heard that even in optimal situation it is more painful than venous sampling. And because it can be more difficult than venous access the doctor may need to do more poking around to get in, which again, hurts.
- When you are taking blood from the radial artery you are effectively occluding it. Thus the hand relies on alternative arteries for blood supply. You can do Allen test (compression of radial and ulnar artery to cut of the blood supply temporary followed by release of ulnar artery to see if circulation to return) to ensure that there will be sufficient blood supply while taking blood. In theory you can cause ischemic damage to the hand if the collateral supply is poor.
- The arteries have much higher pressure than veins and once you have access the blood will be squirting out (hopefully to your syringe). Once you have withdrawn the needle you should apply pressure to the site for several minutes to reduce bruising. While the blood sample is clotting in your syringe becoming increasing useless. So you compromise between bruising and getting the job done.
- When you are having bloods taken it is usually not done by the doctor. Phlebotomists, health care assistants and nurses take large proportion of bloods in both primary care and hospital settings. They generally have not been trained to do (or their job description doesn't include) arterial blood sampling (with perhaps the exception of ICU nurses or specialist respiratory nurses). Thus it requires a doctor, one you may or may not to spare to do arterial sampling when it is not necessary.
- When you are having bloods taken at hospital the doctor or nurse usually uses it as an opportunity to put a line in for fluids and medications. Generally speaking drugs don't go into arteries. Unless you want to lose a limb.

Tetanus
Tetanus_symptoms.jpg
Tetanus often begins with mild spasms in the jaw muscles—also known as lockjaw. More symptoms are in picture.
Treatment :- There's no cure for tetanus. A tetanus infection requires emergency and long-term supportive care while the disease runs its course. Treatment consists of wound care, medications to ease symptoms and supportive care, usually in an intensive care unit.
The disease progresses for about two weeks, and recovery can last about a month.
@Health
Tetanus Causing Bacteria:-
Clostridium-tetani.jpg
Clostridium tetani is an anaerobic bacterium, meaning that it cannot live or grow where oxygen is present. When exposed to air, the bacterium will form a protective spore which allows it to remain in a dormant state, largely impervious to heat, dryness, ultraviolet radiation, or household disinfectants.
The spores can remain viable for years in soil and be reactivated when it is returned to a favorable moist environment. One such environment is a deep puncture wound in which the reactivated bacteria is able to establish an infection.
Once in the body, tetanus will release toxins—known as tetanospasmin toxins —that bind to nerve cells. The toxins will then spread through peripheral nerves until they finally reach the central nervous system (the brain and spinal cord).
As the bacteria multiply and amplify this effect, the tetanospasmin toxins will begin to block the production of certain chemical messengers, known as neurotransmitters, that control voluntary muscle movement.
In terms of toxicity, tetanospasmin toxin is the second deadliest bacterial neurotoxin next to the botulinum toxin found in Botox.
Worldwide, tetanus causes around 60,000 deaths annually.

��Why does Chemotherapy cause hair loss?
Chemotherapy.jpg
Chemotherapy, or chemo, is the use of drugs to stop or slow the growth of cancer cells.
Cancer cells tend to divide very quickly—at a much higher rate than most of the cells in the body. They ignore the signals and mechanisms that tell normal cells to stop dividing.
Some normal cells in our bodies also rapidly divide, like hair follicle cells, the mucous membrane cells lining of the digestive tract (mouth, throat, stomach, intestines), and the blood-producing cells in the bone marrow.
Chemotherapy drugs work by targeting rapidly dividing cells. They damage the genetic material inside cells (RNA and DNA) that guide cell division. Chemotherapy drugs cannot tell the difference between these normal, rapidly dividing cells and cancer cells, so the drug affects these cells as well.
The hair follicles have a good blood supply, which unfortunately allows chemotherapy drugs to reach them efficiently. About 65% of people who receive chemotherapy will experience hair loss. The amount of hair loss can depend on which chemotherapy agent is used, as well as the timing, dose, and route of administration. It can also vary from person to person, and it's hard to predict who will be affected most.

Why does my stomach hurt?
This question is sometimes difficult to answer accurately, even for medical professionals. In about a third of patients, the cause of their ailments can't be determined at all.
This is because there are so many possible causes. The pain may even be psychogenic, meaning that it is caused by stress or the psychological state of the patient.
In the abdominal cavity there are many internal organs and tissues. Pain may be in the intestines, stomach, liver, kidneys, gallbladder and bladder, uterus in women, as well as blood vessels and muscles that cover the abdomen.
And sometimes the problem is not in them at all, but, for example, in the heart - then we talk about irradiating (reflected) pain.
This is why it is so important not to engage in self-diagnosis, but to go to the doctor when you have alarming symptoms. A specialist will assess your well-being, take into account your lifestyle, eating habits, and events that preceded the onset of pain.

Osteoporosis is one of the inevitable diseases for all of us
Osteoporosis.jpg
Sooner or later our bones will become brittle and break more easily.
Osteoporosis affects all bones of the skeleton - there is a marked decrease in bone mass.
This disease manifests itself at the age over 60 (which is when osteoporosis is usually diagnosed). Osteoporosis has severe consequences for patients: chronic pain and prolonged bed rest due to bone fractures.
Bone mass peaks around the age of 30. Therefore, after the age of thirty it is necessary to maintain muscle tone and stimulate bone regeneration with strength exercises.

WHY is blood type B-negative the rarest?
B-negative-blood.jpg
The fourth positive type is much more common. The fourth group in general is a mystery, because it came from the fusion of two very different types, A and B. It is a young group, and people with it have a flexible immune system.
This group is unique in that it emerged not because of the influence of the external environment, but as a result of mixed marriages. It is worth mentioning that this group is the most biologically complex.
⠀
Antigens sometimes make it similar to the second, and sometimes even to the third. Occasionally, it also happens that this rare group is something like a combination of both of these groups.
Thus, the fourth blood group is thought to have appeared later than all the others, about a thousand years ago, as a result of the mixing of Mongoloid and Indo-European.

Mosquitoes carry some of the most dangerous diseases
Mosquitoes.mp4
Malaria, yellow fever, Zika fever, dirofilariosis, meningitis, tularemia...
Perhaps the mosquitoes are most often shadowed by malaria. This is a life-threatening disease, transmitted through the bites of infected mosquitoes - vectors of the genus Anopheles. In the territory of our region this species is almost not found.
However, there is a theoretical possibility that a "normal" mosquito will bite an infected person and then bite another person. In this case, the possibility of malaria transmission is quite high.
How the brain gets tired from mental work
Brain.jpg
The brain uses our body's energy sources, glucose and ATP, even more actively than our muscles!
And at some point the strenuous mental process runs out of ATP. This does not affect muscles and other organs, as they have their own energy depot.
However, the brain notices the lack of energy. This is manifested by distraction, inability to concentrate, temporary deterioration of memory.
This condition can be corrected by a full meal and a healthy sleep, after which the brain "reloads" and is ready to get to work again.

WHY do humans live longer than other mammals?
Live-long.jpg
Scientists may have just discovered a major key to the search for immortality by discovering that our lifespan is inextricably linked to the rate by which our cells undergo genetic mutations.
Although it is logical to assume that our probability of death increases as these mutations accumulate over time, such a hypothesis fails to account for an inconsistency known as the Peto paradox. If death depends on the accumulation of somatic mutations, then larger species with more cells should receive more mutations and therefore have shorter lifespans.
For example, the authors found that human cells undergo an average of 47 replacement mutations per year, giving us an average lifespan of 83.7 years.
How to get rid of muscle pain after a workout?
Muscle-pain.mp4
Muscle pain is caused by two factors: micro-tears, which cause poor circulation and the accumulation of metabolites.
To improve circulation, doctors recommend massage and heat. It is also not superfluous to wear compression knitwear to restore venous blood flow.
Drinking a moderate amount of coffee before exercise also improves venous blood flow, and cherry juice is useful after exercise because it contains antioxidants that reduce inflammation in the muscles.
Heat Stroke (Sun Stroke):-
Heat-stroke.jpg
Severe hyperthermia is defined as a body temperature of 104 F (40 C) or higher. The body normally generates heat as a result of metabolism, and is usually able to dissipate the heat by radiation of heat through the skin or by evaporation of sweat.
🟥 Complications :-
🔸Acute respiratory distress syndrome (ARDS).
🔹Brain swelling.
🔸Kidney failure.
🔹Liver failure.
🔸Metabolic dysfunction.
🔹Nerve damage.
🔸Reduced blood flow to the heart and other circulatory problems.
🩺 Treatments :-
✅ Encouraging them to drink slightly salted fluids, such as sports drinks or salted water.
✅ Having them lay down in a cool, shady, well-ventilated environment.
Immersing them in cool water, if possible.
✅ Misting them with water and blowing air across their bodies (evaporative cooling).
✅ Monitoring their breathing carefully and removing any airway blockages.
✅ Not giving any medications, including aspirin and acetaminophen.
✅ Removing any clothing that is tight or heavy.

Drink more mineral water
To restore the water balance in tissues, a person needs water. But not just any water, but enriched water. Ideally, enriched with magnesium and mineral salts.
Cook protein meals.
White blood cells, the main defenders of our immune system, are made up of proteins. The best and easiest way is to incorporate meals rich in quality protein into your menu. Quality farm meats, fish, and eggs are high in protein and essential micronutrients like iron.
Make up for vitamin gaps.
Iron, zinc, magnesium, calcium, B vitamins and vitamin D are all elements that start to be dramatically lacking if you've recently been sick.
Take care of your microbiota.
Eat fermented foods. These include kefir, farm cheese, sauerkraut, pickles and tomatoes. These contain prebiotics and probiotics, which enrich the gut microflora and benefit all stages of digestion.

Why don't people wake up from their own snoring?
Snoring.jpg
Since even in sleep the brain analyzes sounds, and the sleeper wakes up if the sound is unexpected or has a signal meaning (call, name calling). A person may also be awakened by the absence of a sound, for example, if a night train, which constantly passes by his house at the same time, for some reason did not pass by.
At the same time, the loud but familiar noise does not bother the person, which is known to anyone who has fallen asleep in the subway. Here, too, the snorer's brain does not perceive snoring as an unexpected sound.
Liver.jpg
Fatty liver disease is when excess fat accumulates in the liver. This can happen due to heavy alcohol use. In this case
Fatty liver can progress through four stages:
Simple fatty liver. There's a buildup of excess fat in the liver. Simple fatty liver is largely harmless if it doesn't progress.
Steatohepatitis. In addition to excess fat, there's also inflammation in the liver.
Fibrosis :- Persistent inflammation in the liver has now caused scarring. However, the liver can still generally function normally.
Cirrhosis. Scarring of the liver has become widespread, impairing the liver's ability to function. This is the most severe stage and is irreversible.
Treatment:- The primary treatment for fatty liver disease is to make lifestyle changes that promote liver health. It's possible for the damage caused by fatty liver disease to be reversed when it's treated in its early stages.

Why do women live longer?
Woman-lives-longer.jpg
Yes, this is a statistically proven fact:
Women's average life expectancy is 74 years and 2 months, men's is 69 years and 8 months.
But still, why?
The main reason is genes🧬
Even male embryos die more often than female embryos.
The X chromosomes (of which women have two and men have one) are much larger and contain more vital genes. The Y chromosomes (which only males have) have fewer of these genes.
Therefore, the occurrence of problems in the X-chromosome has greater consequences for men than for women☝🏻.
After all, they have a "spare" X chromosome. It is this reserve that gives women that very advantage.
Besides, we should not forget about peculiarities of men's lifestyle and occupation.
Check your cholesterol levels regularly
Cholesterol.jpg
Cholesterol is necessary for building body cells and other important processes, but when there is too much, it is dangerous. Cholesterol plaques can begin to form on the walls of arteries, which in turn leads to atherosclerosis.
To check your cholesterol levels, take a test once a year. Watch for "bad" (LDL) and "good" (HDL) cholesterol. The former should be no more than 2.6 mmol/L (100 mg/dL), and the latter no less than 1 mmol/L (40 mg/dL).
🐌 Schistosomiasis
Schistomosiasis.jpg
A disease caused by infection with freshwater parasitic worms in certain tropical and subtropical countries.
The parasite can be found in sub-Saharan Africa, the Middle East, Southeast Asia and the Caribbean. The fresh water becomes contaminated from infected animal or human urine or faeces. The parasites penetrate human skin to enter the bloodstream and migrate to the liver, intestines and other organs.
Treatment :- Praziquantel, a prescription medication, is taken for 1-2 days to treat infections caused by all schistosome species.
Diagnosis:- it is diagnosed through the detection of parasite eggs in stool or urine specimens. Antibodies and/or antigens detected in blood or urine samples are also indications of infection.
For urogenital schistosomiasis, a filtration technique using nylon, paper or polycarbonate filters is the standard diagnostic technique. Children with S. haematobium almost always have microscopic blood in their urine which can be detected by chemical reagent strips.

WHY are there many drugs against bacterial infections and few against viral ones?
Virus.jpg
A bacterium is an integral single-celled organism which biochemistry is quite different from that of humans. Therefore, it is possible to find drugs that block the enzymes vital for bacteria or destroy their cell wall, while being harmless or minimally toxic for humans.
A virus, on the other hand, is much simpler, and after infecting the target cell, it has nothing of its own except for the genome. Genome duplication and synthesis of viral proteins are performed by the same molecular mechanisms of the infected cell that ensure the vital activity of healthy cells.
Atherectomy :-

What is Pacemaker?
Pace-maker.jpg
A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat. It's used to help your heart beat more regularly if you have an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires a surgical procedure.
Types of pacemakers-
Depending on your condition, you might have one of the following types of pacemakers.
Single chamber pacemaker.- This type usually carries electrical impulses to the right ventricle of your heart.
Dual chamber pacemaker- This type carries electrical impulses to the right ventricle and the right atrium of your heart to help control the timing of contractions between the two chambers.
Biventricular pacemaker- Biventricular pacing, also called cardiac resynchronization therapy, is for people with heart failure with abnormal electrical systems. This type of pacemaker stimulates the lower chambers of the heart (the right and left ventricles) to make the heart beat more efficiently.
Symptoms that would indicate a blood clot
Blood clots most often form in the lower extremities. One of the most common signs of thrombosis is swelling of the legs.
Also, itching in the legs may increase and the skin takes on a red or blue hue.
Further, the itching develops into pain, and if the clot is in the lower leg area, the person may have cramps.
If there is difficulty breathing, severe coughing, chest pain, and dizziness, it is worth seeking medical attention, as this is an indication that the clot has moved from the legs to the lungs.
Be alert at all times.

What is the difference between Venom and Poison?
IMG_20230802_124255_215.jpg
Venom and Poison are both toxic substances. Still, some animals are called venomous and others are poisonous. The only difference between being called poisonous or venomous is in the way these animals deliver the harmful substance.
Venom: When animals like snakes use their sharp fangs to bite into the flesh and let the toxic substance move into the body of their prey, through the punctured skin, they are called venomous animals. To deliver venom an animal has to use tools like fangs or stingers.
Poison: Poison is something that can get inhaled, ingested or seeped into the skin directly. For example, if you accidentally touch a brightly colored poison dart frog, you will transfer the toxins it secretes from its skin, to your own skin. And then the poison will seep into your blood stream.

What are the dangers of abnormal sugar levels?
Glucose-level.jpg
Both hypo- and hyperglycemia affec how you feel. First of all, the brain suffers, because its cells consume about half of all energy supplied by glucose.
Dizziness, loss of concentration, weakness, darkening of the eyes, and trembling hands are common symptoms for both low and high blood sugar levels.
With constant hyperglycemia, glucose accumulates in organs and tissues and becomes toxic - begins to destroy the liver, kidneys, retina, blood vessels, heart, nervous system.

One of the points of prevention of any disease is always a correction of the diet. And cancer is no exception, because certain foods have been shown to reduce the risk of cancer.
Garlic contains substances that protect against tumors, isothiocyanate, which is found in broccoli, can kill cancer cells and greens expel them from the body.
Also according to studies, citrus fruits, grapes, red wine, blueberries, tomatoes and green tea have anti-carcinogenic properties. So it's worth adding these foods to your diet, but don't overdo it, because you need to be right about everything.
What is a Nephrectomy?
Kidney.jpg
Nephrectomy is the surgical removal of a kidney. The procedure is done to treat kidney cancer as well as other kidney diseases and injuries. Nephrectomy is also done to remove a healthy kidney from a donor (either living or deceased) for transplantation.
There are two types of nephrectomy for a diseased kidney: partial and radical. In partial nephrectomy, only the diseased or injured portion of the kidney is removed. Radical nephrectomy involves removing the entire kidney, along with a section of the tube leading to the bladder (ureter), the gland that sits atop the kidney (adrenal gland), and the fatty tissue surrounding the kidney.
When both kidneys are removed at the same time, the procedure is called bilateral nephrectomy. The procedure used to remove a healthy kidney from a donor for the purpose of transplantation is called donor nephrectomy.

It's just another confirmation that our body is an amazing and complex mechanism.
Epiglottis :-
Without it, we would not be able to breathe and eat!
The epiglottis (epiglottis) is the cartilage that blocks the entry and exit of the larynx (larynx) during the act of swallowing, thereby preventing food from entering the respiratory tract.
Food safely enters the esophagus (esophagus), and air enters the trachea (trachea) ☝🏻
It is the function of the epiglottis that we interfere with when we talk while eating or are in too much of a hurry. Then food enters the larynx, which causes an instant and strong cough reflex.
After all, if a piece of food gets into the lungs, it can cause respiratory failure and even its complete absence.

X-rays are not just for bones
X-rays are designed so that the image is focused on dense tissues. Therefore, the human skeleton is much more visible than the soft tissues. However, the doctor is obliged to assess their condition as well.
The video shows how the configuration of the heart, its curves and the condition of the vessels are determined. In this way, cardiac pathologies, endocarditis or pericarditis can be suspected or confirmed.

How Do Antidepressants Work?
Antidepressant.mp4
The main aim of treatment with antidepressants is to relieve the symptoms of severe depression, such as feeling very down and exhausted, and prevent them from coming back. They are meant to make you feel emotionally stable again and help you to follow a normal daily routine. They are also taken to relieve symptoms such as restlessness, anxiety and sleep problems, and to prevent suicidal thoughts.
The nerve cells in our brain use various chemicals to pass on signals. Even though not all details are known, experts believe that depression is caused by an imbalance of certain chemical messengers (neurotransmitters) like serotonin, which means that signals can't be passed along the nerves properly. Antidepressants aim to increase the availability of these chemicals. The various drugs do that in different ways.
��What Happens When You Drink Too Much Water?
When you drink too much water, you may experience water poisoning, intoxication, or a disruption of brain function. This happens when there's too much water in the cells (including brain cells), causing them to swell. When the cells in the brain swell they cause pressure in the brain. You may start experiencing things like confusion, drowsiness, and headaches. If this pressure increases it could cause conditions like hypertension (High Blood Pressure) and bradycardia (Low Heart Rate).
Sodium is the electrolyte most affected by overhydration, leading to a condition called hyponatremia. Sodium is a crucial element that helps keep the balance of fluids in and out of cells. When its levels drop due to a high amount of water in the body, fluids get inside the cells. Then the cells swell, putting you at risk of having seizures, going into a coma, or even dying.

WHY is blood taken from the ring finger?
The fingertips are easily accessible, hairless, rich in blood vessels, easy to disinfect, and even squeeze if necessary. The skin on the ring finger is thinner than on the thumb, index and middle finger, and contains fewer nerve endings, including pain receptors.
The little finger, on the other hand, is closely connected to the wrist, so if an infection is introduced into a wound on the little finger, it can spread to the bend of the wrist!

🧂 Health checks for diabetes
Tests for diabetes include a fasting blood sugar level test, which measures the amount of glucose in the blood after fasting (not eating for an amount of time). It is usually done before you have breakfast. Depending on your risk level, you will need to be tested annually or once every three years.
🫀 Health checks for your heart:-
To stay healthy and Early detect a upcoming health issue you need to do preventive checkups.
Blood pressure – have your blood pressure checked every two years if it is normal, you are aged under 40 years, and there is no family history of high blood pressure. Have it checked yearly if you are over 40, your blood pressure is on the high side, or you have a personal or family history of high blood pressure, stroke or heart attack. Be advised by your doctor.
Blood tests – check cholesterol levels and blood triglycerides, among other things. High levels may indicate an increased risk of various health problems, including heart disease. If you are over 45, you should have these blood tests once every five years. If you are at high risk of heart disease and have a family history, you should be tested every year from the age of 40.
Electrocardiogram (ECG) – this is a non-invasive and painless medical test that detects cardiac (heart) abnormalities by measuring the electrical activity generated by the heart as it contracts.
Obesity tests – being overweight is a significant risk factor for many health conditions, including cardiovascular disease and diabetes. Ask your doctor to check your body mass index (BMI) and waist measurement every two years. If you are at a higher risk, you should have your weight checked more frequently.
Neumonia.jpg
👃 Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever and difficulty breathing. The severity of the condition is variable.
Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia.
Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough and a weak immune system.
How Many Types Of Injections Are There?
Types-of-injection.jpg
Intramuscular injections:
For injections into muscle tissue, 5-10 milliliter syringes with 6-8 centimeter needles are used or longer for oil-based solutions in order to penetrate deeply. Drugs that are injected by intramuscular injection act more quickly than ones taken orally: the injection is done into muscle tissue that's rich in blood vessels in which to circulate the drug in the blood.
Intradermal injections:
Intradermal injections, or ones which don't go below the dermis, are used for vaccinations. They also help to discover if you have allergies via tests for sensitivity to allergens and they provoke useful intradermal reactions when diagnosing diseases like tuberculosis and brucellosis. What's needed to do them? Maximum 1 milliliter syringes for slow-release drugs with short needles up to 1.5 centimeters.
Subcutaneous injections:
This type of injection is done with a short and fine small needle (1.5 -2 centimeters) and a 2 or 2.5 milliliter syringe. It's recommended for all those substances that need to be absorbed very slowly. A couple of examples? Morphine and atropine. You administer it by inserting the needle almost parallel to the skin until you reach the subcutaneous tissue and that's where the liquid is deposited.
Endovenous injections:
This is a technique where a substance is introduced directly into the circulatory system with a needle inserted into an easily accessible vein: usually these are just below the crook of the elbow or in the lower arm. The main benefit of endovenous injection is that the drug gets administered right into the vein, so any issues of absorption are overcome.
Sweat itself has no odor, but when combined with bacteria and contained in a dark and moist environment, like an armpit, it gives the bacteria a power boost. The medical term for body odor is bromhidrosis.
👨�⚕ Things To Keep In First Aid Box.
🧼1. An antiseptic
To remove any dirt and debris and prevent infection after a minor injury.
🩹2. Adhesive bandage
Accidents happen. Even if you aren't someone who bumps into things all the time, or have kids, waterproof Band-aids or Hansaplast can come in quite handy in a variety of situations. Case in point: shoe bite.
The bandage will prevent your clothes (or shoes) from rubbing against your wound and keep it dry at the same time.
🤕3. Gauze dressing :- Yes, they are a bit old-fashioned. But they're just as versatile as they were in your parents' time.
🩹4. Crêpe bandages :- For sprains and sympathy.
🧷5. Safety pins:- Two reasons: safety pins are versatile - they come in handy for wardrobe emergencies, too; and when you break the clasp on your crêpe bandage, you'll need a safety pin to keep the bandage in place.

✂7. Scissors :- This one's self-explanatory, we think. Just be careful not to cut yourself. And maybe get a babyproof one if you have young children in the house - gauze isn't that hard to cut.
🏐8. Cotton balls and cutips :- Make sure to put them in a clean box within your first-aid box. You won't be doing anyone any favours by using dirty cotton.
🌡9. A thermometer :- Because you can't always use the back of your hand to tell when you're running a temperature. If you have babies at home, this one's a must.
🦟10. Mosquito patch or cream or spray :- To keep five things at bay: dengue, malaria, chikungunya, itchy bites and sleepless nights.
🧴11. Antiseptic cream:- For cuts and scrapes that don't need a bandage. Apply, and forget.
💊12. Painkillers :- Worldwide, headaches and backaches are among the most common reasons why people miss a day of work - keep an appropriate medicine or spray handy.
💈13. Pain reliever spray, gel or balm :-
Pain can get in the way of a good night's sleep. For muscle sprain and back pain, pain reliever spray, gel or balm can ease the discomfort immediately. Yes, you need the spray as well as the painkiller medicine.
💊14. Antihistamines:- To stop the sniffles if you've got allergies, as well as for any allergies you haven't discovered yet.
💊15. Paracetamol:- Be sure to stock up on baby paracetamol if you have kids.
Regular paracetamol is also a mild painkiller.
💊16. Antacid:- Indigestion is more common - and uncomfortable - than anyone would like. A sachet of Eno, a Digene tablet or antacid syrup can help if you're at a pinch. Don't make a habit of it, though. Antacids can harm the kidneys.
🧼17. Eyewash or artificial tears:-
In case your eyes feel gritty or dry after a whole day of looking at the computer screen or because of the polluted air.
🩹18. Pad and/or tampons :-
Just for emergencies, and there are many when it comes to periods. Keep a few pads handy, until you can get to a drugstore.
🦷19. Gel for ulcers and toothache:-
A toothache can hit at any time, without any warning or provocation.
🍼20. Hot water bottle
Not every pain demands to be dealt with pills. Keep a hot water bottle handy for milder aches.
😷21. Air-pollution masks
For when the air turns foul again. The simple, inexpensive N-95 or N-99 mask will do. Either will keep most of the particulate matter in the air out of your lungs.
Share with Others. :) :- Don't go trying to remove a splinter with that safety pin, now. Use tweezers. And if it looks like the splinter is in too deep, don't try to remove it yourself, go to a doctor. A good pair can help you get those eyebrows looking on fleek.
🦟What Eats Mosquitoes?
As mosquitoes are most dangerous insects, Here is list of some hunters of them. @Health
🐤Birds: Many birds will eat mosquitoes. The more important among these are purple martins, swallows, waterfowl (geese, terns, ducks) and migratory songbirds. Bird predators usually eat both the adult and aquatic stages of mosquitoes.

🐠 Fish:- Goldfish, guppies, bass, bluegill and catfish prey on mosquito larvae. But the most important fish predator, by far, is the Gambusia affinis, commonly known as the mosquito fish. This is probably the most effective predator of mosquito larvae and is used by many mosquito control agencies to augment their control efforts.
🐸 Frogs and Tadpoles:- Most adult frogs and tadpoles do not include mosquitoes as a large part of their diet. Tadpoles infrequently feed on mosquito larvae and instead generally feed on small, suspended particles of plant-related materials. However, mosquito larvae predation is known for three species of North American tadpoles – the spade foot toad, green tree frog and giant tree frog. While not a direct act of predation, tadpoles may compete with mosquito larvae for food.
🐢 Turtles:- The red-eared slider turtle is generally thought to be the most voracious turtle that feeds on mosquito larvae.
🐲 Dragonflies:- Dragonflies are often referred to as "mosquito hawks." Though they do eat mosquitoes, they do not eat enough mosquitoes to do much harm to wild populations. One feature that favors dragonflies as mosquito predators is that in the dragonflies' aquatic stage, most of its food consists of mosquito larvae.
🦟 Predacious mosquitoes:- Some mosquitoes prey on other mosquitoes. The most notable being the predatory mosquitoes in the genus Toxorhynchites. These mosquitoes provide a double benefit since the larvae are predacious on other mosquito larvae and the adults are not known to transmit disease.
🕸 Spiders:- become mosquito predators when a mosquito inadvertently flies into a spider's web where it is encased and eaten.

🫀A heart can beat on its own :-
Heart-beat.mp4
The heart does not need a brain, or a body for that matter, to keep beating. The heart has its own electrical system that causes it to beat and pump blood. Because of this, the heart can continue to beat for a short time after brain death, or after being removed from the body. The heart will keep beating as long as it has oxygen.

Facts About Malaria:-
🔸2019, there were an estimated 229 million cases of malaria worldwide.
🔹The estimated number of malaria deaths stood at 4,09,000 in 2019.
🔸Children aged under 5 years are the most vulnerable group affected by malaria; in 2019, they accounted for 67% (2,74,000) of all malaria deaths worldwide.
🔹The WHO African Region carries a disproportionately high share of the global malaria burden. In 2019, the region was home to 94% of malaria cases and deaths.
Appendix Removal
Appendicitis is an inflammation of the appendix, a finger-shaped pouch that projects from your colon on the lower right side of your abdomen.
Appendicitis causes pain in your lower right abdomen. However, in most people, pain begins around the navel and then moves. As inflammation worsens, appendicitis pain typically increases and eventually becomes severe.
CACHEXIA
Cachexia is a "wasting" disorder that causes extreme weight loss and muscle wasting, and can include loss of body fat. This syndrome affects people who are in the late stages of serious diseases like cancer, HIV or AIDS, COPD, kidney disease, and congestive heart failure (CHF).
The difference between cachexia and other types of weight loss is that it's involuntary. People who develop it don't lose weight because they're trying to trim down with diet or exercise
SYMPTOMS :
Cachexia seems to be more common in people with lung cancer or with cancers anywhere in the digestive system. The main symptoms are:
✅severe weight loss, including loss of fat and muscle mass
✅loss of appetite
anaemia (low red blood cells)
✅weakness and fatigue
STAGES:
There are three stages of cachexia—precachexia, cachexia, and refractory cachexia. Not all people will progress through all three stages. Your risk of progression depends on your tumor type and stage, amount of weight loss, presence of inflammation, and severity of anorexia.
CAUSES :
A number of factors contribute to cachexia, including the levels of these substances, the conditions that cause them, and the reaction they provoke from the body.
These substances interact with each other and lead to cachexia through several pathways, including:
✅Increasing metabolism and the spending of energy
✅Causing inflammation
✅Increasing the breakdown of muscle
✅Preventing muscle growth
COMPLICATIONS :
Complications of cachexia include:
✅Diminished quality of life and loss of the ability to live independently
✅Impaired response to treatments
✅Reduced immunity
✅Escalating symptoms of the underlying chronic condition
✅A reduced life expectancy from the underlying disease
TREATMENT :
There is no specific treatment or way to reverse cachexia. The goal of treatment is to improve symptoms and quality of life.
Current therapy for cachexia includes:
✅appetite stimulants such as megestrol acetate (Megace)
drugs, such as dronabinol (Marinol), to improve nausea, appetite, and mood
✅medications that decrease inflammation
✅diet changes, nutritional supplements
✅adapted exercise
WHY do we sneeze?
Sneeze.mp4
Sneezing is a protective reflex triggered when dust or a pungent odor comes into contact with the nasal mucosa. It is a strong and rapid exhalation through the nose.
❗Sneezing allows air to exit at a speed of 1000 km/h, which is equal to the speed of sound.
The same way mucus from a runny nose is expelled.
WHY does motion sickness occur?
Motion-sickness.jpg
It is caused by a malfunction of the vestibular apparatus, responsible for keeping us firmly on feet.
It reacts to changes in the position of the head and body in space, as well as to acceleration.
When a person's body moves and sways in a car or on a boat, the brain receives conflicting information from the different senses, which causes nausea, dizziness, and headaches.
