Which renal vein receives blood from the left gonadal vein and the left suprarenal vein?

• A. Left renal vein
• B. Right renal vein
• C. Inferior vena cava
• D. Aorta

Answer: (A)

Blood from the left gonadal vein and the left suprarenal vein drains into the left renal vein. The left renal vein collects these left‑sided tributaries before continuing to the inferior vena cava, making it the vessel that directly receives both of those veins. The right renal vein, by contrast, does not receive these left‑sided tributaries; it drains the right kidney directly into the IVC, and the right gonadal and right suprarenal veins typically drain into the IVC as well. Remember, the aorta is an artery, not a venous drainage route for these structures.
