The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors.
The way in which the hypothalamus controls body temperature is that  it triggers changes to the sweat glands and muscles.The body can  then increase or decrease the amount â¦ of heat that is lost.rain. There is no specific body part that is made for controlling body temperature, and brain controls all the functions of the body, so it also controls the body temperature â¦ . 4 people found this useful.
