Mr. Yamzeh is confused. Here is the right answer , which I have put in easy to understand steps.
An artery is a tube that carries blood away from the heart.
A vein is a tube that carries blood to the heart.
Arteries : All arteries carry oxygenated blood away from the heart to supply it to the various parts of the body.
Except the pulmonary artery which carries blood to the lungs to get them oxygenated.
Veins : All veins carry de-oxygenated blood from various parts of the body towards the heart .
Except the pulmonary vein which carries oxygenated blood to the heart.
You see the blood comes to the lungs to get oxygenated.
And the blood comes to the heart to be pumped to all organs.
So the pulmonary vein is the only vein to carry oxygenated blood and the pulmonary artery is the only artery to carry de-oxygenated blood.
Hope that gives a clear understanding
