| baroreflex | A negative feedback system which buffers short-term changes in blood pressure. Increased pressure stretches blood vessels which activates pressoreceptors (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. (12 Dec 1998) |

Special nerve cells called baroreceptors are located in the wall of the heart auricles, vena cava, aortic arch and carotid sinuses, and are specialized to monitor changes in blood pressure. If the receptors sense a rise in blood pressure, then, though a negative feedback loop, the heart will slow down to compensate. If they sense a drop in pressure, the heart will speed up. ...
