Q. What is an example of positive feedback of the homeostatic regulation?
In positive feedback the effect caused by an action stimulates the action even more. This is a rarer mechanism of the homeostatic regulation.
An example of positive feedback is the blood clotting process in which each chemical reaction produces enzymes that catalyze the following reaction until the formation of fibrin therefore the products of the antecedent chemical reactions are consumed and the equilibrium of each reaction is dislocated towards the production of more enzymes (a positive feedback).
