cardiovascular reflexes

Cardiovascular reflexes are automatic responses by your nervous system that regulate heart rate and blood pressure to maintain balance. Sensors called baroreceptors detect changes in blood pressure and send signals to the brain, which then adjusts heart rate, the strength of heart contractions, and blood vessel dilation or constriction as needed. These reflexes ensure your blood pressure stays within a healthy range during activities like standing up, exercise, or sudden position changes. They work quickly and automatically to keep your circulatory system stable without conscious effort.
