What are the component parts of a homeostatic control system? Describe a basic function of each
What will be an ideal response?
Components of a homeostatic system include the sensor, which monitors the magnitude of the variable being controlled, and the integrator or control center, which compares the sensor's input with what is considered a normal value (known as the set point) and then sends appropriate signals to the last component of the system (know as the effector). The effector in turn brings about an appropriate change to return the system back to the set point (normal).
