The scientific term for body temperature regulation is thermoregulation. This process involves the maintenance of a stable internal temperature, which is critical for optimal metabolic function. Organisms employ various physiological mechanisms, such as sweating, shivering, and changing blood flow, to adjust their temperature in response to environmental changes. Thermoregulation is particularly vital for endothermic (warm-blooded) animals, as it helps them maintain a constant body temperature despite external fluctuations.
