The Function of the Skin
The skin has many functions, these include: Secretion – The skin secretes sebum from the underlying sebaceous glands. This natural oil helps to keep the skin supple. Heat Regulation – The body temperature is regulated through the skin. Sweating helps to cool the skin while shivering helps to warm the body up. Absorption – Substances can be absorbed through the skin and transported into the bloodstream. Protection – The skin acts as a protective barrier against germs and bacteria. The skin also contains Melanocytes, which produce Melanin, and this helps protect the skin against UV radiation. Excretion – The skin contains sweat glands, which help to excrete excess waste and toxins out of the body. Sensation – The skin contains thousands of nerve endings that act as sensors for pain—heat or cold. Vitamins – The skin helps make Vitamin D, created by a chemical reaction to Sunlight.
