Quizplus · Accepted Answer

The pulmonary arterial circulation delivers unoxygenated blood to the lungs and originates on the right side of the heart. Oxygenated blood is delivered back to the heart through the pulmonary venous circulation. The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs, where it picks up oxygen and becomes oxygenated before returning to the heart through the pulmonary vein. Therefore, only option B accurately describes the function and origin of the pulmonary arterial circulation.
