Eccrine sweat glands are small, coiled structures located in the skin that produce sweat. They are found all over the body, particularly on the palms, soles, and forehead. These glands play a crucial role in regulating body temperature by releasing sweat, which cools the skin as it evaporates. The sweat produced by eccrine glands is mostly composed of water, with small amounts of salts and other substances. Unlike apocrine sweat glands, which are found in specific areas like the armpits and groin, eccrine glands are active throughout life and help maintain homeostasis during physical activity or in hot environments.
