Skin and your health

WHY does a bruise appear and changes its color?

When a bump or bruise occurs, the capillaries are damaged. Blood flows from them into the surrounding soft tissues under the skin. Blood contains plenty of hemoglobin, giving it that bright red color.

White blood cells arrive at the site of the injury. They surround the site of the hemorrhage and begin to destroy the blood cells.

Destruction of hemoglobin produces decomposition products — biliverdin (green bile pigment) and bilirubin (yellow-red bile pigment).

Why scars are so different from normal skin

Scars.mp4

There are two main layers of skin - the epidermis (superficial) and the dermis itself (deep). The epidermis is responsible for constant tissue renewal. Therefore, when skin damage is limited to this layer, the wound heals without a trace.

But when the dermis is affected, a scar is almost guaranteed.

A scar is visually so different from normal skin, because the basal layer of the epidermis responsible for its repair is damaged - the skin cannot be the same.

And the body decides to fill the "gap" with connective tissue, which does not have a complex structure like skin.

Changes in skin color can indicate blood clots



A blood clot makes it difficult for blood to circulate normally. As a result, some blood vessels become full of blood, while others suffer from a lack of blood.

This can be manifested by changes in the color of the skin: in some parts of the affected limb it turns red or blue, in others, on the contrary, it turns pale.

Brittle nails are one of the signs of anemia




Broken nails and poor skin around the nails is one of the telltale signs of iron deficiency anemia.

The condition of the nails in iron deficiency is called "koilonychia", they seem to sink into the skin and become spoon-shaped.

Some Skin Facts.


1. Your skin replaces itself approximately once every 27 days

2. SKIN COLOR IS DETERMINED BY CELLS IN THE EPIDERMIS.

3. YOUR SKIN COULD WEIGH MORE THAN 20 POUNDS(~9 KG).

4. If your skin cells shed every month, how do tattoos stick around? It turns out to be a function of your immune system. The puncture of the tattoo needle causes inflammation in the dermis, the skin's middle layer. In response, white blood cells known as macrophages are sent in to help heal the damage. These macrophages "eat" the dye and can pass it to newer macrophages when they die off, so the pigment is essentially transferred from one cell to another.

5. YOUR BODY'S FLUID BALANCE DEPENDS ON SKIN.

6. A SKIN CONDITION CAN PUT YOU AT GREATER RISK OF OTHER DISEASES.

7. YOUR LEGS MAY BE THE DRIEST PART OF YOUR BODY.

Skin Bacteria



Every square inch of your skin is home to over 32 million bacteria


The most common bacterial skin pathogens are Staphylococcus aureus and group A β-hemolytic streptococci. Herpes simplex is the most common viral skin disease. Of the dermatophytic fungi, Trichophyton rubrum is the most prevalent cause of skin and nail infections.


Keep skin clean.
