-
They took out the first approaches to the human anatomy and physiology
-
Galen found that arteries contained blood, instead of air as had been the belief to that point.
-
the arterial blood was created by venous blood passing from the left ventricle to the right by passing through 'pores' in the interventricular septum, air passed from the lungs via the pulmonary artery to the left side of the heart.
-
This was one of the first works on anatomy, which mentioned hypothesis of heart function and blood circulation.
-
who first described the heart’s valves, and explained that air entered the heart from the lungs where it was transformed into ‘pneuma’, the vital spirit, ‘a most subtle vapor’ to be carried to the body by arteries.
-
described the perpetual movement of blood “with courses of rivers returning to their sources after a passage through numerous channels”.
-
seems to have possessed knowledge of the arteries
-
distinguished veins from arteries but thought that the pulse was a property of arteries themselves.
-
erroneously accepted the Greek notion regarding the existence of a hole in the ventricular septum by which the blood traveled between the ventricles
-
Nafis suggests that the blood reaches the right side of the heart and lungs passes through the pulmonary artery and the lungs is mixed with air and then through the left side through the veins where it expands to the entire body.

-
took great interest in the anatomical structure and physiological workings of the heart.
-
Presents the first exhibition about the movement to be more precise, presenting first concepts of gas exchange and pulmonary circulation
-
Vesalius: also possessed a passion for dissection and partook in the illegal, yet common, practice of body- snatching.
-
published “De V enarum Osteolis” which examined the valves of veins, he aptly described the valves as ‘the little doors of the veins’
