The body has a normal core temperature of 37 degrees, if this temperature rises, a number of things will occur to bring it back down again, this is negative feedback-
1. The detector (in this case the hypothalamus) detects the increase in body temperature.
2. The coordinator (in this case also the hypothalamus) responds, and sends a message to the receptor.
3. The receptor (in this case the sweat glands and arterioles) puts a response in place, for example the sweat glands will begin to produce more sweat, and the arterioles will vasodilate.
4. The body may now become too cool, and the process will begin again.
