What is the function of the renal artery?

• A. Carries blood away from the kidney.
• B. Drains urine from the kidney.
• C. Supplies oxygen to the kidney cortex.
• D. Blood vessel that carries blood to the kidney to be filtered.

Answer: (D)

The renal artery brings blood into the kidney to be cleaned. It branches from the aorta and delivers oxygen-rich blood to the nephrons so filtration can occur, with the cleaned blood exiting the kidney via the renal vein. Urine drainage is handled by the ureter, not the artery, and while arteries do carry blood that supplies oxygen to kidney tissue, the main function highlighted here is delivering blood to be filtered.
