Sweat glands are small, tubular glands in the skin that produce sweat. Their primary function is to regulate body temperature through evaporation. There are two main types: eccrine and apocrine. Eccrine glands are all over the body, producing watery sweat for cooling. Apocrine glands are found in areas with hair follicles, like armpits, and produce thicker sweat that contributes to body odor. Think of sweat glands as your body's personal AC unit. They keep you cool when things heat up!
