How do antagonistic mechanisms manage homeostatic regulation?

How do antagonistic mechanisms manage homeostatic regulation?
by

1 Answer

Answer :

The homeostatic maintenance of the body mostly occurs by means of alternating antagonistic compensatory mechanisms. There are regulators that lower the pH and others that increase it, there are effectors whose function is to increase the body temperature and others that lower it, hormones exist that, e.g., reduce the level of glucose in the blood and others that increase the glycemic level. The use of antagonistic mechanisms is a strategy found by evolution to solve the problem of the maintenance of the body equilibrium.
