Temporal adjustment of the juxtaglomerular apparatus during sustained inhibition of proximal reabsorption
... Tubuloglomerular feedback (TGF) stabilizes nephron function by causing changes in single-nephron GFR (SNGFR) to compensate for changes in late proximal flow (VLP). TGF responds within seconds and reacts over a narrow ...
