How does human skin protect the body?
Quick Answer
Skin acts as a physical barrier, helps regulate temperature, and supports immunity. It is the body’s largest organ.
The Full Story
The outer layer of skin, the epidermis, is packed with cells and lipids that block water loss and entry by microbes. The dermis contains blood vessels, nerves, hair follicles, and glands that help with sensing and cooling. Melanocytes produce melanin, which helps protect DNA from ultraviolet radiation. Skin also contains immune cells that respond to injury and infection.
