- 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? no, positive feedback mechanisms cannot regulate homeostasis no, it is not a negative feedback mechanism no, it does not fit into a classic "push-pull" action no, because it does not result in restoring blood volume O yes, because it is part of a bigger negative feedback mechanism to maintain optimal levels of blood volume.

A person feels satiated after eating a large meal. The blood has plenty of red blood cells.

The circulating fluid flows in one direction (unidirectionally) through a circulatory loop. The circulating fluid is called hemolymph. Ostia are pores in the heart, important for circulatory function. The circulating fluid is called blood. The circulating fluid remains in vessels as it moves throughout the organism. Is the more efficient type of circulatory system.arrow_forwardDescribe in detail the negative feedback mechanism that regulates blood pressure.
