Write about them.

Answer 1

Pulmonary vein and pulmonary artery are those veins and arteries that carry blood to and fro lungs.

They are different from other veins and arteries because generally arteries carry oxygenated blood and veins carry deoxygenated blood but in case of pulmonary vein and pulmonary artery it is just the reverse.
Pulmonary artery carries deoxygenated blood whereas pulmonary vein carries oxygenated blood.
