Quizplus · Accepted Answer

The pulmonary arterial circulation delivers deoxygenated blood to the lungs and originates on the right side of the heart. It is important to note that oxygenated blood returns to the heart via the pulmonary veins, not the pulmonary arteries. Therefore, option 1 is incorrect. The pulmonary artery is the only artery that carries deoxygenated blood, and it originates on the right ventricle of the heart, hence option 4 is correct. Option 3 is incorrect because pulmonary circulation originates on the right side of the heart, not the left.
