Question

Quizplus · Accepted Answer

Extrinsic control of the GFR is not an autoregulatory mechanism, as autoregulation refers to the ability of the kidney to maintain a constant GFR despite changes in blood pressure or flow. Extrinsic control is mediated by factors outside of the kidney, such as sympathetic nervous system activity, and is aimed at regulating arterial blood pressure by adjusting renal blood flow and GFR.
