Renal autoregulation of the kidney shoud not be confused – regarding their mechanisms - with the regulation of circulating volume, though RAS seems to play a role in both of them (not proven in case of autoregulation so far, however)
The circulating volume is homeostased mainly by means of the endocrine RAS against disturbing factors such as loss or overplus of water, salt etc. (Fig.20)
