One of the functions of the Integumentary System is the negative feedback, homeostatic control of the core body temperature. This is called thermoregulation.
The circulatory system also helps our bodies maintain a constant temperature. As blood flows past. cells heat will move from the blood to the cells -or- the other way from the cells to the blood. This exchange of heat keeps all the body parts at the same temperature.
