who first described the circulation of blood?

Answer 1

In 1242 the Arab scholar Ibn Nafis became the first person to accurately describe the process of blood circulation in the human body. Contemporary drawings of this process have survived. In 1552, Michael Servetus described the same, and Realdo Colombo proved the concept, but it remained largely unknown in Europe.

Finally William Harvey, a pupil of Hieronymus Fabricius (who had earlier described the valves of the veins without recognizing their function), performed a sequence of experiments and announced in 1628 the discovery of the human circulatory system as his own and published an influential book about it. This work with its essentially correct exposition slowly convinced the medical world. Harvey was not able to identify the capillary system connecting arteries and veins; these were later described by Marcello Malpighi.

Answer 3

Your all wrong. Primarily because the only person to believe the heart pumped blood, who was important, was an American: William Hagen. However, for his theory, the AMA took his license away and called him a quack. Go figure.
P.S. Extra credit for whoever can tell me where the term "Quack" came from.
