Homeostasis involves a stimulus-response model in which changes in the conditions of the external or internal environment are detected, and appropriate responses occur via negative feedback.
When the body detects a change in the external or internal environment, it sends signals to a control center, usually the brain or a specific organ. The control center then determines the appropriate response and sends signals to the effectors, which are muscles or glands that carry out the response.
Negative feedback is a mechanism by which the body returns the conditions back to a set point or normal range. For example, if body temperature increases, the control center will send signals to the sweat glands to produce sweat and the blood vessels to dilate, allowing heat to dissipate from the body. As a result, the body temperature decreases, and the control center detects this change, signaling the effectors to stop the response.
This stimulus-response model and negative feedback loop help maintain a stable internal environment, allowing the body to function properly despite external influences or internal fluctuations.
