Which English physician discovered the mechanism of blood circulation?
Pulmonary circulation at birth, the pulmonary pressure drops and blood is drawn from the right atrium into the right ventricle and through the pulmonary circuit. Over the course of several months, the foramen ovale closes, leaving a shallow depression known as the fossa ovalis. A number of medical conditions can affect the pulmonary circulation. The discovery of pulmonary circulation has been attributed to several scientists over the years. In much of modern medical literature, the discovery is credited to English physician William Harvey (1578 - 1657 CE). Other sources credit Spanish physician Michael Servetus (c. 1509 - 1553 CE) and Arab physician
Pulmonary circulation circulation reflected the incorrect views of Galen. The arab physician, Ibn al-Nafis, wrote the "Commentary on Anatomy in" "Avicenna's" "Canon" in 1242 in which he provided the first known accurate description of pulmonary circulation as it is known today. Ibn al-Nafis made two key improvements on Galen's ideas of pulmonary circulation. First, he disproved the existence of the pores in the interventricular septum that Galen had believed to allow blood flow between the left and right ventricles. Second, he followed that the only way for blood to get from the right to the left ventricle in the absence of interventricular
