Verified step by step guidance

Step 1: Understand the pathway of blood flow in the kidney. Blood flows through a series of vessels to reach the glomerulus, which is part of the nephron responsible for filtration.

Step 2: Recall the sequence of blood vessels in the kidney. Blood enters the kidney through the renal artery, then flows into the segmental arteries, followed by the interlobar arteries, arcuate arteries, and interlobular (cortical radiate) arteries.

Step 3: Identify the role of the arcuate artery. The arcuate artery is located at the boundary between the renal cortex and medulla, and it branches into the interlobular (cortical radiate) arteries.

Step 4: Recognize that after passing through the arcuate artery, blood flows into the interlobular (cortical radiate) arteries, which supply blood to the afferent arterioles leading to the glomerulus.

Step 5: Note that the renal vein, afferent arteriole, and efferent arteriole are not part of the immediate pathway after the arcuate artery. The interlobular (cortical radiate) artery is the correct vessel in this sequence.
