Final answer:
The C. hypothalamus is responsible for thermoregulation in the body.
Step-by-step explanation:
The C. hypothalamus is responsible for thermoregulation in the body. It acts as the body's thermostat, regulating the core temperature by initiating processes to either cool down or warm up the body.
If the temperature is too high, the hypothalamus increases blood circulation to the skin and initiates sweating to cool the body. On the other hand, if the temperature falls below the set core temperature, the hypothalamus can initiate shivering to generate heat.
