apocrine vs. eccrine

apocrine vs. eccrine: What's the difference?

Apocrine and eccrine are both types of sweat glands. Eccrine glands are found all over the body and secrete a thin, watery sweat that cools the skin. Apocrine glands are found in the armpits and perineal areas, and are attached to hair follicles. The latter secrete a thicker sweat, which is acted on by bacteria to produce the all-too-familiar “sweat smell."
