In cardiovascular physiology, the<unk>  or baroreceptor reflex is one of the body's homeostatic mechanisms for maintaining blood pressure. It provides a negative feedback loop in which an elevated blood pressure reflexively causes blood pressure to decrease; similarly, decreased blood pressure depresses the<unk> , causing blood pressure to rise.
The system relies on specialized neurons (baroreceptors) in the aortic arch, carotid sinuses, and elsewhere to monitor changes in blood pressure and relay them to the<unk> ainstem. Subsequent changes in blood pressure are mediated by the autonomic nervous system.
