Baroreceptors in the feedback system that control blood pressure sense changes in?

Baroreceptors in the feedback system that control blood pressure sense changes in the stretch of the arterial walls, which occurs due to variations in blood pressure. When blood pressure rises, the walls of the arteries stretch more, leading to increased firing of baroreceptors. Conversely, a drop in blood pressure results in decreased stretch and reduced baroreceptor activity. This information is relayed to the central nervous system, which adjusts heart rate and vascular resistance to maintain stable blood pressure.
