<P> The clear secretion produced by eccrine sweat glands is termed sweat or sensible perspiration . Sweat is mostly water, but it does contain some electrolytes, since it is derived from blood plasma . The presence of sodium chloride gives sweat a salty taste . </P> <P> The total volume of sweat produced depends on the number of functional glands and the size of the surface opening . The degree of secretory activity is regulated by neural and hormonal mechanisms (men sweat more than women). When all of the eccrine sweat glands are working at maximum capacity, the rate of perspiration for a human being may exceed three liters per hour, and dangerous losses of fluids and electrolytes can occur . </P> <P> Eccrine glands have three primary functions: </P> <Ul> <Li> Thermoregulation: sweat cools the surface of the skin and reduces body temperature . </Li> <Li> Excretion: eccrine sweat gland secretion can also provide a significant excretory route for water and electrolytes . </Li> <Li> Protection: eccrine sweat gland secretion aids in preserving the skin's acid mantle, which helps protect the skin from colonization from bacteria and other pathogenic organisms . </Li> </Ul>
