Quizplus · Accepted Answer

Regulated variables, such as body temperature or blood pH, are kept within normal range by physiological control mechanisms. These mechanisms use a setpoint, which is the ideal value for the regulated variable. If the variable strays too far from the setpoint, the control mechanisms will activate to bring it back to the setpoint. Therefore, regulated variables are kept within normal range by control mechanisms which use the setpoint as a reference.
