A review of the normal anatomy and physiology of eccrine sweat glands and sweating may be found in Chapter 83. Sweat gland functions Each one of these portions or segments of the sweat gland have a specific function: 1) as its name implies, the secretory segment is responsible for the production of sweat - without the hard work of these little sweat gland components, we would all be in serious trouble: our bodies would heat up (hyperthermia) and damage to our vital organs would result. This mechanism of unbound cortisol partitioning and salivary rate independence found in salivary gland function can be speculated to be true for sweat glands as well. FUNCTION OF SWEAT GLANDS Thermoregu lat ion Sweating is one of man's major mechamsms of evaporative heat loss, and man shares with a few other primates the primacy of sweating as a con- trolled evaporative heat loss mechanism.
