MeSH definition : A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches
BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response
of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This
reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering
CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can
compensate rapidly for both increases and decreases in blood pressure.;
