• A. Renal artery, interlobar artery, interlobular artery, arcuate artery, efferent arteriole, glomerulus, afferent arteriole, peritubular capillaries
• B. Renal artery, arcuate artery, interlobar artery, interlobular artery, efferent arteriole, glomerulus, afferent arteriole, peritubular capillaries
• C. Renal artery, interlobular artery, arcuate artery, interlobar artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries
• D. Renal artery, interlobar artery, arcuate artery, interlobular artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries

Answer: (D)

Verified step by step guidance

1. Begin with the renal artery, which is the main blood vessel that supplies blood to the kidneys.
2. The blood then flows into the interlobar arteries, which are branches of the renal artery that run between the renal pyramids.
3. Next, the blood moves into the arcuate arteries, which arch over the base of the renal pyramids.
4. From the arcuate arteries, blood flows into the interlobular arteries, which extend into the renal cortex.
5. The blood then enters the afferent arterioles, which lead to the glomerulus, a network of capillaries where filtration occurs. After filtration, blood exits through the efferent arterioles and flows into the peritubular capillaries, which surround the renal tubules.
