Raas negative feedback
WebDec 1, 2015 · The RAS is primary regulated by a negative feedback effect of angiotensin II on renin production by the juxtaglomerular cells of the renal afferent arteriole . Angiotensin II receptors The physiological effects of angiotensin II result from its binding to specific G protein-coupled receptors. WebSep 12, 2024 · In particular, the overall system can be seen as the feedback of the monotone subsystem, formed by the variables in the smooth muscle cell compartment, with three distinct negative feedback loops. Indeed, variable x 16 has an inhibitory effect on x 1 , while x 17 has an activating effect on x 1 ; x 1 has an activating effect on x 16 and an inhibitory …
