Final answer:
Alveoli facilitate oxygen exchange with blood, pulmonary veins carry oxygenated blood, and the pulmonary artery transports deoxygenated blood to the lungs.
Explanation:
Alveoli are the structures in the lungs where gas exchange takes place, allowing oxygen to move from the lungs into the bloodstream. Oxygenated blood is then carried from the lungs to the rest of the body by pulmonary veins. The pulmonary artery carries deoxygenated blood to the lungs for oxygenation.
