Skin [skĭn]
The thin layer of tissue forming the natural outer covering of the body of a person or animal.

Your skin is not just a coating; it is your body's largest organ. It is waterproof, helps keep germs out, and protects your inner organs. It has nerve endings that tells you how things feel, and it provides cushioning and temperature control for your body. Different skin colors are determined by the amount of melanin bodies have — the more melanin, the darker the skin.
