The chequered career of galen's doctrine on the pulmonary veins

Abstract

By its heat and continuous motion, the lung further concocts the blood brought to it through the arterylike vein [pulmonary artery], and renders it foamier, such as that [blood] already is which reaches the lung through the veinlike artery [pulmonary vein] from the left ventricle of the heartt since it has already been elaborated in both ventricles of the heart.
