Sweat glands

Sweat glands are tiny organs in your skin that produce sweat, a fluid mainly made of water, salts, and waste products. They help regulate your body temperature by releasing sweat onto the skin's surface, which cools you down when it evaporates. There are two types: eccrine glands, found all over the body, and apocrine glands, located in areas with more hair, like the armpits and groin. These glands also play a role in skin health and immune defense. Overall, sweat glands are essential for maintaining your body's temperature and removing certain wastes.
