Here's how it works:
* Sweat Glands: When the body temperature rises, sweat glands release sweat onto the skin's surface. As the sweat evaporates, it takes heat energy with it, cooling the body down.
* Blood Vessels: When the body gets too hot, blood vessels near the skin's surface dilate (expand). This allows more blood to flow close to the surface, allowing heat to radiate away from the body.
While other systems like the respiratory system (exhaling warm air) and the urinary system (excreting some heat in urine) play a role, the integumentary system is the primary mechanism for heat removal.
