The is the part of the body responsible for regulating body temperature.

Hypothalamus

Explanation:

Hypothalamus is the thermoregulatory center of the human body. It maintains the temperature homeostasis. When any changes in temperature from outside and inside the body occur, the hypothalamus maintains the temperature constancy. When there is more heat, the thermoregulatory center stimulates the sweat gland and reduces excess heat from the body. Similarly, when there is colder the body starts to shiver to retain body heat. Thus the normal 37-degree celsius temperature of the body is always maintained.
