Verified step by step guidance

Understand the anatomy of the kidney: The renal artery is the main blood vessel supplying the kidney. It branches into smaller arteries as it enters the kidney to distribute blood to different regions.

Identify the sequence of blood flow: Blood flows from the renal artery into progressively smaller arteries. The first branch after the renal artery is the segmental arteries, which supply specific segments of the kidney.

Clarify the role of segmental arteries: Segmental arteries are responsible for dividing the blood flow into different regions of the kidney, ensuring efficient distribution to the renal cortex and medulla.

Recognize the subsequent branches: After the segmental arteries, blood flows into the interlobar arteries, arcuate arteries, and finally the interlobular arteries, which lead to the afferent arterioles supplying the glomeruli.

Review the options provided: Based on the sequence of blood flow, the correct answer is 'segmental,' as it is the first branch after the renal artery in the renal sinus.
