Question

Renal artery

• A. Enters the kidney from aorta
• B. Enters posterior vena cava from kidney
• C. Leaves the kidney and enters into posterior vena cava
• D. Leaves the lungs and enters into kidney

Answer 1

The correct option is A Enters the kidney from aorta

The renal arteries normally arise off the left interior side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle.

So, the correct option is 'Enters the kidney from aorta'.
