What are the functions of skin?

Skin is a barrier that prevents germs (pathogens) from entering your body. It is also responsible for temperature control. The skin:
  • Cools the body temperature by dilating blood vessels, allowing heat to escape and opening sweat glands to let water out.
  • Keeps the body warm by constricting blood vessels and keeping the body’s heat inside.
Receptors in the skin allow us to feel pressure, pain, heat and cold.
