Ibn_al-Nafis_and_the_Discovery_of_Pulmonary_Circulation.pdf [click file name to view]
The major original contribution of Ibn al-Nafis that had a great significance in history was his discovery of the pulmonary circulatory, which was re-discovered by modern science after a lapse of three centuries. He was the first to correctly describe the constitution of the lungs and give a description of the bronchi and the interaction between the human body's vessels for air and blood. Also, he elaborated the function of the coronary arteries as feeding the cardiac muscle.
