Skin

The body’s largest organ, the skin has an area of about 20 square feet in a human adult. It weighs about 10 pounds. The skin is your body’s gatekeeper against the outside world and the first line of defense of the immune system.

Skin contains 3 layers — the epidermis, or outer layer; the dermis, or thick inner layer; and the hypodermis, or cushioning fat layer.
