• (Miguel Servet or Miguel Serveto also Miguel De Villanueva or Michel De Villeneuve) • Servetus was the first European to describe the function of pulmonary circulation • His interests included many sciences: theology,mathematics ,cartography, astronomy and meteorology, geography, human anatomy, medicine and pharmacology, as well as jurisprudence, and the scholarly study of the Bible in its original languages
pulmonary circulation flows from the heart to the lungs (rather than air in the lungs flowing to the heart as had been thought in Galen’s system). His discovery was based on the color of the blood, the size and location of the different ventricles, and the fact that the pulmonary vein was extremely large, which suggested that it performed intensive and transcendent exchange. • Servetus does not talk just about cardiology. he also talks of the brain, the cerebellum, the meninges, the nerves, the eye, the tympanum, etc.
