An example of a positive feedback mechanism is blood clotting in which certain clotting factors active other factors until a plug forms to stop bleeding. Is this process involved in homeostasis? O no, positive feedback mechanisms cannot regulate homeostasis O no, it is not a negative feedback mechanism O no, it does not fit into a classic "push-pull" action O no, because it does not result in restoring blood volume O yes, because it is part ofa bigger negative feedback mechanism to maintain optimal levels of blood volume.
