Hi there,
Most of the body heat is regulated by the hypothalamus in your brain. Your hypothalamus functions as the set-point, the reference, that your body should be.
The hypothalamus constantly gets information send to it from heat-detecting nerves in your body. If the information it receives differs from the setpoint, it will attempt to change it.
If your body is to hot, arteries near your skin surface open to radiate the heat out. You'll start sweating, your respiration speed might go up. It also affects you conciously - you feel warm.
If your body is to cold, arteries near the skin surface shut down to keep the heat inside. You'll start to shiver - the shivering motion caused by your muscles generate heat. You'll also feel the cold, obviously.
So the regulator would be your hypothalamus, which is also it's coordination system. The monitors would probably be the nerves/sensors in your body that can measure temperature.
The feedback system would be negative. The Hypothalamus detects the difference -> Starts to send out signals to bring it back to normal -> Once organ is back to normal, cease this activity of the hypothalamus.
If it were to be a positive feedback it would probably not snap out of it.. Although I must admit I'm not quite sure on the feedback thing.
