Structure and Function

Skin is the largest organ of the body, and serves to:

  • Protect against injury

  • Protect against the sun UV rays

  • Prevent entry of harmful microorganisms

  • Maintain the proper internal body temperature

  • Excrete waste materials through perspiration (sweat)

Two main layers of skin

Structure and Function

Two Main Layers of Skin

  • Skin (epidermis) – outer most layer

  • Dermis – Nerves, vessels, glands, hair follicles


Hair

Structure and Function

Hair

  • Hair grows out of the epidermis to cover parts of the body.
