Control Systems

A control system is a group of cells and organs that work together to maintain homeostasis.

  1. Receptor: detects changes in the environment
  2. Coordination Centre: interprets signals from the receptor and sends responses to the effector
  3. Effector: carries out the response, reversing the effect of the change
