Answer:
Thermoregulation
Step-by-step explanation:
Our body has different mechanism to maintain body temperature in the specific levels for its proper functioning. That range goes between 36.5–37.5 °C (97.7–99.5 °F) and the hypothalamus is the area in our brain that controls this homeostatic process. When our body senses heat, blood vessels dilate and skin begins to sweat to lose heat. When our body senses cold, blood vessels constrict to avoid heat loss and muscles shiver to produce heat.
