B) right atrium → aorta → renal artery → kidney → renal vein → hepatic portal vein → vena cava → left atrium
C) left ventricle → renal artery → kidney → renal vein → vena cava → right atrium
D) left ventricle → aorta → renal artery → kidney → renal vein → vena cava → right atrium
E) right ventricle → aorta → renal artery → kidney → renal vein → vena cava → hepatic portal vein → right atrium

Question

Quizplus · Accepted Answer

The correct pathway of blood from the heart to the kidneys and back to the heart again is left ventricle → aorta → renal artery → kidney → renal vein → vena cava → right atrium. Choice A is incorrect because it incorrectly places the vena cava before the renal vein, and the renal vein leads to the vena cava. Choice B is incorrect because it includes the hepatic portal vein, which is not part of the pathway between the heart and kidneys. Choice C is incorrect because it incorrectly places the renal artery after the left ventricle, and the artery is actually a branch of the aorta. Choice E is incorrect because it places the right ventricle before the aorta, when blood leaves the left ventricle to enter the aorta.
