How do Sweat glands help regulate body temperature?

Maintenence of a stable body temperature requires that the amount of body heat lost is balanced by the amount produced. Heat is a product of cellular metabolism; thus, the more active cells of the body are the major heat producers. These cells include the skeletal and cardiac muscles cells and the cells of certain glands, such as the liver. As the body temperature rises, nerve impulses stimulate structures in the skin and other organs to release heat.
