Introduction

Baroreceptors are a type of mechanoreceptor allowing for the relay of information derived from blood pressure within the autonomic nervous system. Information is then passed in rapid sequence to alter the total peripheral resistance and cardiac output maintaining blood pressure within a preset, normalized range.

There are two types of baroreceptors:

1. High-pressure arterial baroreceptors and low-pressure volume receptors which are both stimulated by stretching of the vessel wall. Arterial baroreceptors are located within the carotid sinuses and the aortic arch.
2. Low-pressure volume receptors, or cardiopulmonary receptors, are located within the atria, ventricles, and pulmonary vasculature
