Final answer:
Eccrine sweat glands are distributed across the skin's surface and produce a dilute, salty sweat for thermoregulation.
Step-by-step explanation:
An eccrine sweat gland is a type of gland that produces a dilute, salty sweat for thermoregulation in humans. These glands are distributed across the surface of the skin and are especially abundant on the palms of the hand, the soles of the feet, and the forehead. The sweat produced by eccrine glands is hypotonic and composed mainly of water, with some salt, antibodies, traces of metabolic waste, and an antimicrobial peptide called dermicidin.
