Eccrine Sweat Gland

Type of sweat gland that is widely distributed throughout the body. Eccrine sweat glands function in thermoregulation by removing heat through sweat evaporation. Humans are notable for the large number of these glands, which are sparse in other primates; it is felt by many that eccrine glands helped early hominids adapt to a warm environment on the African savannas and were associated with a decrease in body hair. The glands produce a liquid that consists mainly of water and salt, with a saline concentration; see sweat. Aka eccrine gland.

Cf. apocrine sweat gland.
