The Skin is the largest organ of the body. The skin functions in a number of different ways to protect us from external elements such as:
Prevents the absorption of harmful substances.
Helps regulate the body temperature.
Acts as a barrier to keep out infection.
Melanin in the skin protects us from the harmful effects of UV light.
Provides a waterproof coating that prevents us from becoming dehydrated.
Provides an energy reserve in the form of stored fat.
