Question 16

78. What are the functions of the pulmonary arteries and pulmonary veins?

Answer 16

The pulmonary veins connect to the left atrium of the heart. The heart pumps oxygen-depleted blood into the lungs via the pulmonary arteries. Once the blood has been oxygenated, it returns to the heart via the pulmonary veins. The pulmonary arteries deliver oxygen-depleted blood to each corresponding lung. This is one of the rare arteries that carry deoxygenated blood; the other location is found within the fetus.
