It helps to regulate body temperature, it protects the skin, the body form microorganisms, it helps to regulate body fluids, it also is a site of the metabolism of important nutrients. The three layers of the skin include the epidermis, the dermis and subcutaneous fat. The epidermis is the outermost layer of the skin. It is the site of pigment production or melanin and keratin which is responsible for the firmness and the rigidity of the skin. The second layer of the skin is the dermis. It is divided into the papillary dermis and the reticular dermis. The upper layer is the papillary dermis. The lower layer is the reticular dermis which contains blood vessels and nerves.
