Explain how sweat glands can help the human body to cool down.
Answer
Sweat glands play a critical role in thermoregulation by producing sweat. When the body temperature rises, the sweat glands secrete sweat onto the surface of the skin. As the sweat evaporates, it absorbs heat from the body, which results in cooling. This process is essential for preventing overheating, especially during physical activity or in hot environments, allowing the body to maintain a stable temperature.
