The region of the distal tubule that monitors concentration of the filtrate is called the
A) vasa recta
B) collecting duct
C) macula densa
D) mesangial
E) extraglomerular

Question

Quizplus · Accepted Answer

The macula densa is a region of the distal tubule that monitors the concentration of the filtrate passing through it. It plays an important role in regulating the glomerular filtration rate (GFR) by signaling to the juxtaglomerular cells in the afferent arteriole to adjust the diameter of the arteriole and regulate blood flow to the glomerulus.
