Final answer:
When the body overheats, it attempts to cool down through mechanisms such as vasodilation and sweating. Severe overheating can lead to heat exhaustion or heat stroke.
Step-by-step explanation:
When the body overheats, it goes through a series of physiological responses to try to cool down and maintain homeostasis. One of the first things that happens is that blood vessels near the skin surface dilate, allowing more blood to flow near the skin and releasing heat through radiation. Additionally, the body may produce sweat, which when evaporated, helps to cool down the body. If the body continues to overheat, it may lead to symptoms such as dizziness, fatigue, and cramps. In severe cases, heat exhaustion or heat stroke can occur, which can be life-threatening.
