What would happen to a person who has damaged pulmonary veins?

Pulmonary veins carry oxygen-rich blood from the lungs to the heart’s left atrium. If they are damaged, that blood would not return to the heart normally, so it could not be pumped out to the rest of the body as it should. Therefore, the correct choice is “Oxygenated blood would not get back to the heart to be pumped all over the body.”
