Verified step by step guidance

Step 1: Understand the anatomy of the kidney's blood supply. Blood flows through a series of vessels in a specific order to ensure proper filtration and function. The renal artery is the main vessel that brings blood into the kidney.

Step 2: Identify the correct sequence of blood flow. The renal artery branches into segmental arteries, which further divide into interlobar arteries. These arteries travel between the renal pyramids.

Step 3: Next, the interlobar arteries branch into arcuate arteries. These arteries arch over the bases of the renal pyramids, forming a boundary between the cortex and medulla.

Step 4: The arcuate arteries then give rise to interlobular arteries, which extend into the renal cortex. These smaller arteries supply blood to the nephrons, the functional units of the kidney.

Step 5: Review the correct order of blood flow through the kidney: Renal artery → segmental artery → interlobar artery → arcuate artery → interlobular artery. This sequence ensures efficient blood delivery for filtration and kidney function.
