The tubuloglomerular feedback mechanism that results in the macular densa cells responding to the filtrate’s high sodium concentration by releasing paracrine agent, that causes vasodialation diameter of the afferent arterioles and reduces blood flow. WebPurpose of review: Autoregulation of renal blood flow has traditionally been considered to stabilize glomerular filtration, and thus tubular load, in the face of blood pressure fluctuations.
