Because it returns from the lungs where it has picked up oxygen.

Pulmonary Vein

A vein is a blood vessel that carries blood TO the heart, FROM other organs. The pulmonary vein brings blood from the lungs after oxygenation. Other veins come from other parts, where the oxygen has already been used by the organs. But the lungs dont use up the O2, they just supply it to the pulmonary vein.
so, it is the only O2 rich bein.

Apart from carrying oxygen-rich blood from lungs to the heart, which is the cause and not the actual reason.
According to developmental biology, it is the only vein that opens to the left auricle, which is related to the systemic circulation of the body. Hence it should carry oxygen-rich blood to the heart from the lungs to fulfil the purpose of its anatomical position.
Thus it is the only vein in the body that carry oxygen-rich blood to the heart from the lungs unlike other veins.
Thank you.

pulmon means "lungs" in latin. so pulmonary means the vessel that comes from the heart and vein means it enters into the heart. from lungs it carries oxygenated blood to the heart. other veins bring deoxygenated blood to heart. thats why pulm.vein is the only oxygen-rich vein in body

The pulmonary artery takes the used-up Carbon dioxide to the lungs. There, it is replaced with pure Oxygen. It is the task of the pulmonary vein to then take the pure Oxygen to the heart to be circulated.

because all other veins carry deoxygenated blood BACK to the heart to be sent to the lungs to pick up oxygen. the pulm vein, brings oxygen rich blood from the lungs back to the heart to be sent round the body

What that guy said first, but you should also be aware that it is sending oxygen rich blood to the heart which in turn sends that oxygen rich blood to the arteries. Veins are transporters of carbon dioxide rich blood. That vein just happens to be in the middle.

blood after purification from the lungs is carried by it while the rest of the other veins carry the deoxygenated blood. hence it is only the oxygen rich vein of out whole body.

The pulmonary artery (not the vein) carries oxygen rich blood it receives from the lungs to your heart. From there the heart distributes the oxygen rich blood throughout the rest of your body. Think of the heart as a huge pumping machine.
You inhale oxygen and exhale cabon dioxide that is released by the lungs from the oxygen deprived blood that makes its way back to your lungs after delivering the oxygen to various parts of your body. For the most part arteries carry oxygenated blood and veins carry the unoxygenated blood.

That vein is connected to the lungs so therefore it is the vein that carries oxygen throughout your body.
