How does the skin keep us healthy?

skin keeps us healthy by protecting our blood to be infected by bacteria, and keeping us warm. Our skin has many different layers, all with different jobs. The epidermis- the part of the skin on the outside of your body- the part you can see
dermis-where blood vessels and nerves are at work
hypodermis-mostly made of fat- is where your hair grows
