Low pressure baroreceptors have both circulatory and renal effects, which produce changes in hormone secretion. Stimulation of these receptors causes the atria to release atrial natriuretic peptide. This hormone acts on the kidneys to increase sodium excretion, which increases urine production and thereby leads to a decrease in blood pressure.
Baroreceptors are integral to the body's function: Pressure changes in the blood vessels would not be detected as quickly in the absence of baroreceptors. When baroreceptors are not working, blood pressure continues to increase, but, within an hour, the blood pressure returns to normal as other blood pressure regulatory systems take over. [11]
Their function is to sense pressure changes by responding to change in the tension of the arterial wall. [1] The baroreflex can begin to act in less than the duration of a cardiac cycle (fractions of a second) and thus baroreflex adjustments are key factors in dealing with postural hypotension , the tendency for blood pressure to decrease on ...
Atrial volume receptors (also known as Veno-atrial stretch receptors [1]) are low pressure baroreceptors that are found in the atria of the heart. They are myelinated vagal fibres in the endocardium found at the junction between atria and the vena cava/pulmonary vein.
There are two kinds of baroreceptors: high-pressure arterial baroreceptors and low-pressure volume receptors, both activated by the stretching of vessel walls. [7] Arterial baroreceptors are situated in the carotid sinuses and the aortic arch, while the low-pressure volume receptors, known as cardiopulmonary receptors, are in the atria ...
Mayer waves are cyclic changes or waves in arterial blood pressure brought about by oscillations in the baroreceptor reflex control system. [1] [2] The waves are seen both in the ECG and in continuous blood pressure curves and have a frequency about 0.1 Hz (10-second waves).

The carotid sinus baroreceptor can be oversensitive to manual stimulation from the pressure applied at the carotid sinus at the carotid bifurcation. It is a condition known as 'carotid sinus hypersensitivity' (CSH), 'carotid sinus syndrome' or 'carotid sinus syncope', in which manual stimulation causes large changes in heart rate and blood ...
