Homeostasis

• What are the three main components of control systems in the body?


  Receptors, coordination centres, and effectors
• How does negative feedback work in the body?


  It counteracts changes to restore the optimum level
• What are the steps involved in the negative feedback process?


  1. Receptor detects a stimulus
  2. Coordination centre receives information
  3. Effector produces a response
  4. Response counteracts the change and restores the optimum level
• What might happen if effectors continue to produce responses without regulation?


  It could cause the levels to change too much away from the ideal
