" what if we want to change gfr ? (cid:8869) t blood volume due to drinking fluids. T gfr corrects the t blood volume (cid:8869) d. blood volume due to blood loss. " mediated by t or d in sns input to the renal arterioles afferentm efferent. Gc: afferent anethole more blood t poc vasodilation in gc, afferent arteriolar vasoconstriction. Vasodilation of s d gc blood efferent anethole volume. T poo: vasoconstriction of efferent arteriole. At low levels of vasoconstriction the gf rt. " at higher levels of vasoconstriction the gfr d. At low blood how s toc t. " as the filtrate leaves the hoo gin::himation blood flow rates. " toc increases and that opposes filtration ( poo - pbs) - o (tt od. " sns input tends to induce vasoconstriction in afferent arteriole more than the exe rent anethole (cid:8869) vasoconstriction of afferent anethole. 4 maybe the vasoconstriction of the ekerent anethole prevents a massive drop in gfr.
