Baroreceptor

are specialized mechanoreceptors—sensory nerve endings that act as the body's primary "pressure sensors" for maintaining circulatory balance. They are integral to the baroreceptor reflex , a rapid negative-feedback loop that stabilizes blood pressure (BP) and heart rate from moment to moment. Core Anatomy and Types

There are two primary categories of baroreceptors, distinguished by their location and the pressure levels they monitor: baroreceptor
