Skin Anatomy Howstuffworks When your skin gets cut, your body springs into action to heal the wound. first, the body works to limit blood loss by reducing the amount of blood flowing to the wounded area. proteins in blood, such as fibrin, work with the blood platelets already in place and plasma to form a protective covering called a scab. Subcutaneous tissue. your skin has three layers that each serves an important purpose. though you cannot see it, the innermost layer is composed of subcutaneous tissue, an all important insulator that regulates your body’s temperature and protects your insides. by sarah siddons.
How Your Skin Works Howstuffworks Sun and aging thicken the outer layer of skin, and as the tide of skin cells rises, they form a tiny volcano rim around pores. this makes pores seem bigger than they really are. oily looking skin tends to make pores look larger. washing your face regularly to cut down on oiliness will improve their appearance. Of course, this estimate can vary tremendously according to a person's size. the important thing is that you have a lot of skin cells. of those billions of skin cells, between 30,000 and 40,000 of them fall off every hour. over a 24 hour period, you lose almost a million skin cells [source: boston globe]. Function of sebum. sebum has many purposes. once this oily substance makes its way to the surface of your skin, it keeps your skin waterproof. it's a barrier in two ways: it keeps too much water from getting into your body, and it prevents you from losing too much water through your skin. sebum also protects skin from bacterial and fungal. The average person has 2.6 million sweat glands in their skin. sweat glands are distributed over the entire body except for the lips, nipples and external genital organs. the sweat gland is in the layer of skin called the dermis along with other "equipment," such as nerve endings, hair follicles and so on.

The process takes a few weeks, but eventually the cells will divide until they've created a sheet of skin 100 times the size of the original sample [source: singer]. while skin cells that keep dividing are cancerous, the skin sheets have so far returned to normal once engrafted. sometimes, the lab grown skin is treated with an antibacterial. The sweat they secrete a yellowish, thick fluid happens in response to stresses. body odor is the byproduct of bacteria on your skin digesting the sweat produced by apocrine glands. but there are no apocrine glands on your feet. eccrine glands, on the other hand, are located in the skin all over your body, including your feet.
