What Is the Function of a Sweat Pore?

The function of a sweat pore is to provide a duct for the release of sweat from the sweat glands, notes Everyday Health. There are between 2 and 4 million sweat glands across the entire body.

There are two different types of sweat glands. Eccrine glands are located all over the body with the exception of areas such as the lips and nipples. These pores help the body regulate heat. Whenever the body becomes too warm, the eccrine glands release sweat to cool down the body.

Apocrine glands are located in hair follicles and are commonly found in areas such as the underarms, head and groin area. The apocrine glands are responsible for reacting to heat as well as anxiety and stress. When a body is under duress, the apocrine glands excrete a fatty sweat through the hair follicle. The breakdown of the fatty sweat by bacteria on the skin is what causes body odor, notes Everyday Health. Sweat consists of mostly water and sodium with a small amount of other materials.

The human body contains one other type of pore: the hair follicle. Hair follicles also contain sebaceous glands which create an oily substance used to lubricate the skin. Acne is formed when these pores are blocked, notes Everyday Health.
