Illustration of negative feedback of homeostatic regulation

Question

What is an illustration of negative feedback of homeostatic regulation?

Answer 1

Negative feedback occurs whenever the response to a particular action produces an effect which inhibits that action. For illustration, whenever the carbon-dioxide concentration in blood is high then the pulmonary respiration is stimulated for CO₂ excess to be expelled via expiration. Hyperventilation, though, lowers the carbon-dioxide concentration in blood too much producing a negative feedback which commands the decrease of respiratory frequency.

Negative feedback is the main method of homeostasis and it takes place in a variety of processes, like in glycemic control, blood pressure control, muscle contraction and so on.
