During renal autoregulation, the glomerulus receives feedback from
A) juxtaglomerular cells
B) podocytes
C) smooth muscle cells
D) macula densa
E) mesangial cells

Question

Quizplus · Accepted Answer

The macula densa is a specialized group of cells in the distal convoluted tubule that detect changes in the sodium chloride levels and regulate the blood flow to the glomerulus through the juxtaglomerular apparatus. The juxtaglomerular cells are located in the walls of the afferent arteriole and secrete renin, an enzyme that helps regulate blood volume and pressure. Podocytes are cells that make up the filtration barrier of the glomerulus. Smooth muscle cells are found in the walls of arterioles throughout the body, including the afferent and efferent arterioles of the kidney. Mesangial cells are located in the glomerulus and help regulate blood flow and filtration. However, the macula densa is the primary site for feedback during renal autoregulation.
