The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. Wounding affects all the functions of the skin.
Why is skin so important?
Your skin is the organ that comes into contact with the rest of the world. It holds body fluids in, preventing dehydration (dee-hahy-DREY-shun), and keeps harmful microbes (MYE-krobs) out—without it, we would get infections.
