In humans, apocrine and merocrine sweat glands form the primary method of cooling.
Sweat glands are usually either merocrine (most common) or apocrine (a specialized merocrine gland usually found around armpits that may be responsible for body odor and potentially human pheromones).

Sweat glands (sudoriferous glads) are distributed over the entire skin surface except the nipples and parts of the external genitalia. There is 2 types of sweat glands: eccrine and apocrine. Eccrine (merocrine) sweat glands are more numerous and particularly abundant on the palms, soles of the feet, and forehead. Each is a simple, coiled, tubular gland. Apocrine sweat glands are mostly found to the axillary and anogenital areas. They are merocrine glands, which release product by exocytosis like eccrine sweat glands. Oil (sebaceous) glands are found all over the body except in the thick skin of the palms and soles. They're simple branched alveolar glands.
