The receptors located in the heart, aortic arch, and carotid sinuses that trigger autonomic reflexes in response to fluctuations in blood pressure are known as Baroreceptors.
Baroreceptors are present in the carotid sinus and the aortic arc and regulate the blood pressure levels in the body. Whenever blood pressure increases or decreases the stretch receptors present in the blood vessels send signals to the brain.
The brain interprets them and send signals to other parts of the body like kidney and heart. The kidney and heart releases enzyme like erythropoietin and atrial natriuretic factor respectively that regulate the blood pressure accordingly.
