Quizplus · Accepted Answer

The pulmonary circuit refers to the circulation of blood between the heart and the lungs. It involves the pulmonary arteries which move deoxygenated blood to the lungs, where it gets oxygenated, and then the oxygenated blood returns to the heart through the pulmonary veins. The hepatic portal vein is part of the systemic circuit, which involves the circulation of blood between the heart and the rest of the body. The coronary arteries supply blood to the heart itself and are also part of the systemic circuit. Therefore, choices A and C are incorrect. Choice E is incorrect because it includes all of the options, but option B (moves oxygenated blood to the lungs) is incorrect as the pulmonary circuit moves deoxygenated blood to the lungs. The best answer is D, which correctly states that the pulmonary circuit leads to, through, and from the lungs.
