Eccrine sweat glands can be found over the majority of the body and produce the fluid that cools the human body known as sweat. Apocrine sweat glands can be found in greater density in the armpits and produce a different type of sweat that when metabolized by bacteria produces a distinctive and often unpleasant odor.
'The secretory portion of the sweat gland resides in the deeper parts of the dermis and produces the salty proteinand-lipid-rich fluid known as sweat.'
