Abstract
The role of cardiopulmonary receptors in the control of renal sympathetic nerve activity and of renin release is reviewed. The evidence indicates that cardiopulmonary receptors with vagal afferents exert a tonic inhibition on both renal nerve activity and on renin release. The magnitude of this inhibition appears directly related to changes in blood volume. Atrial as well as ventricular receptors can influence the secretion of renin. Cardiopulmonary receptors with vagal afferents may also reflexly modulate renal prostaglandin secretion. There is preliminary evidence to suggest that cardiopulmonary receptors with sympathetic afferents can influence renal nerve activity. The limitations of previous studies are outlined and a direction for future studies is suggested. It is concluded that alterations in cardiopulmonary vagal afferent input and the resulting changes in renal nerve activity and in renin release are appropriate for the maintenance of blood volume homeostasis.
