Which is not a blood vessel associated with the kidney?

A)efferent arteriole
B)vasa recta
C)macula densa
D)glomerulus
E) afferent arteriole

C)macula densa

The correct answer is D) glomerulus.

Explanation:

The glomerulus is a part of the blood vessel network within the kidney. It is a tuft of capillaries that is responsible for filtering blood in the first step of urine formation. The glomerulus is associated with the filtration process in the kidney rather than being a separate blood vessel.

On the other hand, the efferent arteriole, afferent arteriole, vasa recta, and macula densa are all blood vessels associated with the kidney.

The afferent arteriole brings blood into the glomerulus, while the efferent arteriole carries blood away from it. The vasa recta is a network of capillaries surrounding the tubules in the kidney that regulates blood flow and exchanges substances. The macula densa is a specialized group of cells in the distal convoluted tubule that monitors the composition of the filtrate.
