[change] The Integumentary System

The Integumentary System is the system of the body made up of the skin, the nails, and the hair.

Skin keeps you cool by sweating. It also protects you by keeping things out of your body. The hair on your body keeps you warm. Skin also holds nerves that we use to touch and hold and kiss.
