Region of the distal tubule that monitors concentration of the filtrate.
A) vasa recta

Question

Quizplus · Accepted Answer

The macula densa is a specialized cluster of cells located in the wall of the distal tubule near the glomerulus. These cells monitor the concentration of the filtrate and act as chemoreceptors, signaling to the juxtaglomerular cells in the afferent arterioles to adjust the rate of glomerular filtration accordingly.
