Which vessel carries blood to the kidney?

• A. Renal vein
• B. Renal artery
• C. Aorta
• D. Inferior vena cava

Answer: (B)

Blood reaches the kidneys through the renal arteries. These vessels branch off the abdominal aorta and deliver oxygen-rich blood to the kidney’s nephrons for filtration. After processing, blood exits via the renal veins and returns to the heart through the inferior vena cava. The aorta supplies arterial branches to many organs, but the specific vessel that carries blood directly to the kidney is the renal artery, while the renal vein and inferior vena cava carry blood away from the kidney.
