Question

Quizplus · Accepted Answer

The mean arterial pressure is constantly monitored by baroreceptors, which are specialized stretch receptors located in the walls of certain blood vessels, particularly in the carotid sinus and aortic arch. These receptors detect changes in blood pressure and send signals to the brain, which in turn adjusts heart rate, blood vessel diameter, and other factors to maintain blood pressure within a range suitable for normal physiological function.
