Homestasis is achieved by
a: Stimulus receptor control centre effector response
stimulus
any disruption
Receptor
sensor that monitors the bodys internal & external environment for changes
Control centre
determines what appropriate actions need to be taken and when it need to start and stop responses
Effector
muscles or glands that bring about the response
response
Negative or positive feedback
Negative feedback
Prevents sudden and severe changes within the body and once achieved reduces response to shut of control process such as heating or cooling
Positive Feedback
Enhances and amplifies the change so that control process continues at even faster rate until stimulus is removed e.g breast feeding
