Video - Baroreceptors

Baroreceptors are a type of mechanoreceptors that sense changes in blood pressure, and send signals to the brain that control heart rate and vascular tone. When blood pressure rises, baroreceptor activity increases, which leads to a decrease in heart rate and an increase in vascular tone.

When blood pressure falls, baroreceptor activity decreases, leading to an increase in heart rate and a decrease in vascular tone. There are two types, arterial, and cardiovascular baroreceptors. Arterial baroreceptors are located in high-pressure regions, namely in the aortic arch, and the carotid bodies, whereas cardiovascular baroreceptors are located within the heart's atria, ventricles, and pulmonary vessels.
