Human Skin Challenge – The Body's Protective Cover

Skin is the body's largest organ, covering about 2 square meters in adults. It protects against germs, injury and water loss, helps control temperature and lets us feel touch, heat and pain.

Skin has layers. The epidermis on top constantly renews itself, the dermis below holds blood vessels, nerves, hair follicles and glands and a fatty layer underneath cushions and insulates. Melanin gives skin its color and protects against UV rays.

Skin also makes vitamin D in sunlight and heals wounds remarkably. Sunscreen, moisturizing and gentle care protect it, while doctors check unusual spots for skin cancer.
