WebBaroreceptors are stretch receptors and respond to the pressure induced stretching of the blood vessel in which they are found. Baroreflex-induced changes in blood pressure are … WebA baroreceptor (also known as a pressoreceptor) is a neuron that is sensitive to stretch and is located in the aorta and carotid sinus. Baroreceptors are sensitive to small changes in blood pressure and respond to these changes rapidly. WebThe physiologic responses to a reduction in central blood volume involve baroreflex-mediated increases in heart rate (HR) and vascular resistance to adequately maintain arterial pressure and cerebral perfusion.
