What are the physiological processes of vasodilation and sweating when the body temperature is too high?

When body temperature rises, vasodilation occurs, which is the widening of blood vessels near the skin surface. This allows more blood to flow to the skin, facilitating heat loss. Additionally, sweating is triggered, where sweat glands release moisture onto the skin's surface, which cools the body as it evaporates.

This answer is strong because it clearly describes both processes involved in thermoregulation when the body overheats, demonstrating an understanding of physiological responses. The question tests the student's ability to recall and explain specific biological mechanisms.
