Skin, the large external organ in the human body is the outer layer, with a total area of about 20 square feet which protects the internal organs, bones, and tissues against damage.
The skin processes 3 main layers
* Epidermis is the outermost layer of the skin providing a barrier against infection from environmental pathogens. The outer layers also regulate the amount of water released from the body through transepidermal water loss.
* Dermis is the second layer of skin, containing blood capillaries, nerve endings, sweat glands, hair follicles, and other structures.
* The bottom layer is the subcutaneous fat which has been found to process the protective effect against the dangers of visceral fat.
