Which of the Following are the Blood Vessels at the Boundary

Question

Which of the following are the blood vessels at the boundary of the renal cortex and renal medulla?
A) interlobar artery and vein
B) cortical radiate artery and vein
C) glomerular artery and vein
D) segmental artery and vein
E) arcuate artery and vein

Accepted Answer

The vessels at the boundary of the renal cortex and renal medulla are the arcuate artery and vein, which run along the boundary between the two regions. The interlobar artery and vein are located between the renal pyramids and supply blood to them. The cortical radiate artery and vein are found in the renal cortex and supply blood to the nephrons. The glomerular artery and vein are part of the nephron and supply blood to the glomerulus. The segmental artery and vein are larger vessels that branch off the renal artery and vein and supply blood to different regions of the kidney.
