Renal Baroceptor Control of Renin Secretion

Abstract

Small reductions in renal perfusion pressure to levels still within a physiologic range, which did not reduce renal blood flow, caused the kidney to release renin. Renin appeared in much larger amounts in renal-vein blood than in renal lymph. Release of reruin appears to be mediated by a renal baroceptor rather than by ischemia.
