Explain the autoregulatory mechanism of GFR.
Answer:
Autoregulation is a fundamental component of renal function. The kidneys have built-in mechanisms for the regulation of glomerular filtration rate. It is mediated by juxtaglomerular apparatus. Juxtaglomerular apparatus is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. A fall in GFR activates the Juxtaglomerular cells. It leads to the release of renin, which stimulates the glomerular blood flow and thereby the GFR returns back to normal.
