Which of the following takes place when a person’s body temperature rises above 37oC

When a person's body temperature rises above 37°C, sweating and vasodilation take place. The body has a natural mechanism to regulate its temperature called thermoregulation. When the body temperature rises above its normal range, sweat glands located in the skin become active, and the sweat they produce evaporates from the skin, cooling the body down. This is known as sweating. In addition, the blood vessels in the skin widen or dilate, known as vasodilation. This increases the blood flow to the skin, which allows the heat to escape from the body more efficiently. Therefore, sweating and vasodilation work together to cool down the body when its temperature rises above the normal range. This helps to prevent overheating and maintain the body's internal temperature within a safe range.
