Control Systems
Biology: Cambridge International GCSE Supplement, topic 14.4.3
Control Systems
Control systems use both nervous and chemical responses. Control systems are made up of three parts:
Receptors
- Receptor cells detect changes in the environment.
Coordination centres
- Coordination centres receive and process information arriving from receptor cells.
Effectors (muscles or glands)
- Effectors (muscles or glands) carry out responses to stimuli (events or things) that help to restore optimum levels.
