Sweat Gland Structure, Function and Distribution

There are between 2 and 4 million sweat glands found across the human body. These are coiled tubular glands that are found in the dermis or lower part of the skin.
They produce a watery secretion and open on to the skin to help control body temperature and provide an emotional response to stimulus. When you sweat the moisture on your body evaporates and provides a cooling effect for the body.

There are two types of sweat glands, eccrine sweat glands and apocrine sweat glands. Both types of glands are controlled by the sympathetic nervous system, which controls many of our involuntary actions such as breathing, heartbeat and sweating.
