These simultaneous effects act to create a gradient for sodium and water reabsorption.
WebIntervention in the renin-angiotensin-aldosterone-system (RAAS) is associated with slowing the progressive loss of renal function. During initiation of therapy, however, there may be an acute fall in glomerular filtration rate (GFR). We tested whether this initial fall in GFR reflects a renal hemody … WebJan 1, 2002 · Although angiotensin II (ANGII) exerts an important influence on the mean level of renal blood flow (RBF) and contributes to the fine tuning of glomerular filtration …
WebThe renin-angiotensin system plays an important role in the regulation of glomerular filtration. A decrease in renal plasma flow is followed by an increase in glomerular efferent arteriole resistance, so that perfusion pressure and glomerular filtration remain constant. Furthermore, if the decrease in renal plasma flow is more marked ...
WebAngiotensin I is converted to Angiotensin II by ACE in the lung.
