In the innumerable branches of this artery, expanding themselvesthroughout the, substance of the lungs, the dark blood is subjected tocontact of the air inhaled in breathing; and a change in the composi-tion, both of the blood and the inhaled air, takes place, in consequenceof w hich the former is found to have reassumed its florid or arterialhue, and to have regained its power of supporting life. The blood Of the Thorax, or Chest. 353 then enters the myriads of minute venous ramifications, which grad-ually coalesce into larger branches, and at last terminate in four largetrunks, two from each lung, and empty themselves into the left auricle,from which the blood is thrown into the left ventricle, and from thisthrough the great aorta, which divides itself again into myriads of ar-teries, greater and smaller, through which the purified or arterial bloodis distributed to every part of the body, however minute.
