The renal arteries originate at which vertebral level?

Explanation:
Renal arteries arise from the abdominal aorta as paired lateral branches. Their usual origin is at the level of the second lumbar vertebra (L2), just below the origin of the superior mesenteric artery. This location fits the kidneys’ retroperitoneal position opposite L1–L2 and is above the aortic bifurcation (around L4). Embryologically the kidneys migrate upward from the pelvis, but in the adult the main renal arteries typically come off the aorta around L2. Variations can occur (accessory arteries), but L2 is the classic level.
