Baroreceptors can be divided into two categories based on the type of blood vessel in which they are located: high-pressure arterial baroreceptors and low-pressure baroreceptors (also known as cardiopulmonary or volume receptors).rterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes.
