Skin Cells

they are 3 layers of skin. the epidermis, the dermis and the hypodermis. the epidermis is the outer layer of your skin that you can see. it protects the outside of your body. the dermis is under the epidermis. the dermis contains nerve endings, oil glands and sweat glands.

the dermis has lots of blood vessels. the blood vessels keep the skin cells healthy by bringing the, the oxygen and nutrients they need and by taking away waste. The third layer is the hypodermis. it is made up of mostly fat and help your body stay warm and absorb shock.
