Final answer:
The body's control system for maintaining homeostasis involves a sensor, control center, and effector.
Step-by-step explanation:
The body's control system performs three actions to maintain homeostasis:
- Sensor: A receptor detects changes in the internal or external environment and sends signals to the control center.
- Control center: The control center receives signals from the sensor and determines the appropriate response.
- Effector: An effector carries out the response dictated by the control center to restore homeostasis.
