One of the functions of the Integumentary System is the negative feedback, homeostatic control of the core body temperature. This is called thermoregulation.
How our body maintains a constant temperature. Temperature receptors in the skin detect changes in the external temperature. They pass this information to the processing centre in the brain, called the hypothalamus. The processing centre also has temperature receptors to detect changes in the temperature of the blood.The processing centre automatically triggers changes to the effectors to ensure our body temperature remains constant, at 37Â°C. The effectors are sweat glands and muscles.he processing centre also has temperature receptors to detect changes in the temperature of the blood.
