What are the two main types of sweat glands?

The two main types of sweat glands in the human body are eccrine and apocrine glands. Eccrine glands are found all over the body and are primarily responsible for regulating body temperature through the secretion of water. They play a critical role in thermoregulation, especially during exercise or in hot environments, as their secretions evaporate and help cool the skin.

Apocrine glands, on the other hand, are primarily located in specific areas such as the armpits and groin. These glands become active during puberty and their secretions are associated with body odor since they produce a thicker fluid that is rich in proteins and fatty substances. While they do play a role in temperature regulation, their primary function is linked more to pheromonal signaling than simple thermoregulation.

Both types of glands are important but serve distinct roles in maintaining homeostasis and skin health. Recognizing these differences reinforces the understanding of how the integumentary system functions in diverse physiological contexts.
