In the pulmonary circuit,which structures contain the highest blood pressure?

Question

Quizplus · Accepted Answer

The pulmonary artery contains the highest blood pressure in the pulmonary circuit because it is responsible for carrying blood from the heart to the lungs, where it undergoes gas exchange. The pressure in the pulmonary artery is higher than in the pulmonary veins because it has to overcome the resistance of the lungs to pump the blood through them. The aorta carries blood from the heart to the systemic circulation and has the highest blood pressure in the systemic circuit. The pulmonary veins carry oxygenated blood from the lungs to the heart, and the right atrium receives deoxygenated blood from the systemic circulation. The lungs themselves do not contain blood pressure, but rather they are the site of gas exchange.
