Right renal artery arises from the _______ lateral aspect of the aorta.

Right renal artery arises from the _______ lateral aspect of the aorta.

• A. Anterior
• B. Posterior
• C. Superior
• D. Inferior

Answer: (A)

The kidneys receive their blood supply from renal arteries that branch off the abdominal aorta. These vessels come off the lateral surface of the aorta and head toward each kidney, with the right renal artery arising from the anterolateral (anterior) aspect. This orientation explains how the artery courses toward the hilum of the right kidney. The other directions would not match the usual origin from the front-facing lateral surface of the aorta.
