The main function of the sweat gland of mammalian skin is to control body temperature through water evaporation from the skin. This process is known as thermoregulation. When the body temperature rises, sweat glands release sweat onto the skin's surface. As the sweat evaporates, it takes heat away from the body, thus cooling it down.
This mechanism is crucial for maintaining a stable internal body temperature, especially during physical activity or hot weather conditions.
