- A communication system between receptors and effectors , which may be far apart from one another, allows the organism to:
- Monitor changes in the internal and external environment.
- Respond adaptively to such changes
- Coordinate the activities of different organs
- Homeostasis is the maintenance of a relatively stable internal environment within an organism. This provides relatively constant conditions for the individual cells, even when the external environment fluctuates or the organism changes its behaviour.
- Homeostasis requires:
- A receptor (sensor or detector) that recieves information (input)
- A control mechanism that responds to information and stimulates an effector.
- An effector to perform the appropriate action.
- Input > receptor > control mechanism > effector > output >…
