>> ABOUT SKIN

 

WHAT IS SKIN ?

The largest and heaviest organ of your body.
The characteristics: soft, pliable, strong, waterproof and self repairing.

HOW MUCH SKIN HAVE I GOT ?

An adult may have more than 20 square feet (1.8m2) of skin – about the size of a blanket. The surface of the skin is constantly renewed. You are likely to shed around 40 pounds of skin in a lifetime.

HOW THICK IS MY SKIN ?

The thickest skin is on the soles of the feet and on the back where it can measure up to 5 mm (nearly ¼ of inch), whereas the thinnest skin is around the eyes and is a tenth as thick as the skin on the back (0.5 mm).
Small children have much thinner skin all over their body, compared to adults.

WHAT DOES THE SKIN DO ?

Your skin does not just cover you! It does a lot more.
Is a protective wrapping. Skin and the fat layer underneath it, insulate our body against wear and tear, cold temperatures.
Keeps the germs and water out and keeps fluids and salt in. Skin processes its own oils and wax in order to have waterproof quality. Your skin sweats through some glands and eliminates chemicals that your body wants to get rid of and cool the body when evaporate.
We feel the objects around us with the nerves in the skin, particularly using the hands where there are a lot of sensory receptors.

HOW MANY LAYERS DOES A SKIN HAVE ?

Skin has a surface layer of alive and dead cells called epidermis. The next layer underneath is called dermis and contained sweat glands, hair roots, glands that produce oils and has blood vessels and nerves. The thickness of epidermis and dermis varies throughout the body. Underneath dermis is the fat layer.
