Communication and Homeostasis

Communication

• 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

• 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 >…
