why is the pulmonary vein called a "vein" when it is dumping into the left atrium then aortic valve going to the aorta??? I mean once the blood leaves the lungs it is red and it is an artery... I just don't get the logic... furthermore, they do it again with the Pulmonary artery... which lol, at this point it has lost its O's and is blue and going to the lungs... aren't these names backwards???? LOL, I am not trying to change the world here but it seems a little goof to me.
