The pulmonary artery, as has already been noted, conveysvenous or impure blood from the heart to the lungs, whilethe pulmonary veins convey arterial or purified blood fromthe lungs to the heart. The pulmonaryveins are four innumber, two fromeach lung openinginto the left auricleof the heart. Theupper right pul-monary vein passesfrom the root ofthe right lung be-hind the superiorvena cava, and thelower right pul-monary vein be-hind the right auri-cle, both to end atthe upper and backpart of the rightmargin of the leftauricle. Both theupper and the low-er left pulmonaryveins pass from theroot of the left lungin front of the de-scending aorta, toend at the u
