Vesalius Proved Servetus and Estienne Right
Vesalius found one of only three remaining copies, then published Servetus’s findings along with his own. He proved the septum is waterproof, then discovered and named the mitral valve while explaining blow flow. He then proved Charles Estienne’s findings on the valves of the hepatic veins.
Vesalius added information on the Azygos Vein, then discovered the canal that connects to a fetus between the Umbilical Vein and Vena Cava. All of this is considered factual to this day and is taught to medical students all over the world. Without Andreas, we would have believed old thoughts for perhaps hundreds of more years.
