==Low-pressure baroreceptors==
{{See also|Low pressure receptors}}
The low-pressure baroreceptors are found in large systemic [[vein]]s, in pulmonary vessels, and in the walls of the right atrium and ventricles of the [[heart]] (the [[atrial volume receptors]]).<ref name="Stanfield, CL 2008 pp.430-431" /> The low-pressure baroreceptors are involved with the regulation of blood volume. The blood volume determines the mean pressure throughout the system, in particular in the venous side where most of the blood is held.

The low-pressure baroreceptors have both circulatory and renal effects; they produce changes in [[hormone]] secretion, resulting in profound effects on the retention of [[osmoregulation|salt and water]]; they also influence intake of salt and water. The renal effects allow the receptors to change the long-term mean pressure in the system.
