Servetus, Michael (1553). Christianismi restitutio … (in Latin). Vienne, France: Baltasar Arnoullet. p.170. Available at: Biblioteca Digital Hispánica – Biblioteca Nacional de España From p. 170: "Fit autem communicatio hæc non per parietem cordis medium, ut vulgo creditur, sed magno artificio a dextro cordis ventriculo, longo per pulmones ductu, agitatur sanguis subtilis: a pulmonibus præparatur, flavus efficatur: et a vena arteriosa, in arteriam venosam transfunditur." (However this communication [of blood from the right to the left ventricle] occurs not through the middle wall of the heart, as is commonly believed, but by a great mechanism, the subtle blood is driven from the right ventricle of the heart, [and] at length led through the lungs; it is made ready in the lungs, is made yellowish, and is [thus] transferred from the pulmonary artery into the pulmonary vein.)
