Chemistry of Sweat
     Perspiration or sweat is your bodies way of cooling itself. It consists of water and certain dissolved substances produced by glands in the skin. These glands are called sweat glands. The average person has 2.6 million sweat glands in their skin. Sweat glands are spread out all over the human body. They are in the layer of skin called the dermis. The sweat gland is a long coiled tube of cells. The coiled part is a duct that connects the gland to the opening or pore on the skins outer surface. Nerve sells from the sympathetic nervous system connect to the sweat glands in the body.
