heart
lungs
. similarly, a defect in pulmonary veins may lead to a block in the supply of oxygenated blood to the
dropdown
.

Explanation:

1. For the first drop - down: The pulmonary artery carries deoxygenated blood from the heart to the lungs. So a defect in the pulmonary artery would affect the supply of deoxygenated blood to the lungs.
