Question

Blood vessels of the renal columns are called ________.

1) lobar
2) segmental
3) interlobar
4) cortical radiate

Answer 1

The blood vessels found in the renal columns are called interlobar arteries, and they play a critical role in renal blood supply by branching from the segmental arteries to the cortex.

Step-by-step explanation:

The blood vessels of the renal columns are called interlobar arteries. These arteries arise from the segmentation of the renal artery into segmental arteries, which then further divide into interlobar arteries that traverse the renal columns to reach the renal cortex. The interlobar arteries continue to branch into arcuate arteries, followed by cortical radiate arteries, which in turn branch into afferent arterioles to service the nephrons. The renal veins trace the path of these arteries and have similar naming, except for the absence of segmental veins.
