What physiological response occurs when the body is hyperthermic?

• A. Shivering
• B. Vasoconstriction
• C. Sweating
• D. High heart rate

Answer: (C)

When the body is hyperthermic, which means it is experiencing an elevated internal temperature, the physiological response that primarily occurs is sweating. Sweating is a crucial mechanism that helps regulate body temperature by encouraging heat loss through the evaporation of sweat from the skin surface. As sweat evaporates, it absorbs excess heat from the body, leading to a cooling effect. This process is vital for maintaining homeostasis, especially during exercise or exposure to high temperatures. Additionally, sweating is typically accompanied by increased blood flow to the skin through vasodilation, which allows for more efficient heat dissipation. This response works in conjunction with the overall objective of thermoregulation, while shivering and vasoconstriction are responses associated with hypothermia and the preservation of heat rather than the management of high body temperatures.
