Question

Quizplus · Accepted Answer

The baroreceptor reflex primarily regulates perfusion pressure, which refers to the pressure at which blood is pushed through the circulatory system to reach tissues and organs. Baroreceptors, located in the walls of the carotid sinuses and aortic arch, detect changes in blood pressure and send signals to the brain to trigger adjustments in heart rate and vascular resistance, ultimately aiming to maintain a stable perfusion pressure. While the baroreceptor reflex indirectly affects cardiac output and tissue perfusion, these are not its primary targets.
