Not to enter into too much detail, or in too minute dissection, for the time does not permit. Harvey did quantify blood flow, but his quantification is very approximate, and he deliberately used underestimates to further his case.

It also should be noted that much of his terminology for change was drawn from the alchemy of his time. It provoked immediate controversy and hostility from the medical community of the time, contradicting as it did the usually unquestioned teachings of Galen.

Eventually, Harvey was also elected Treasurer of the College.

Accessed 26 February Cambridge University Press, The same effect was seen in other veins of the body, except the veins in the neck. The blood has come back to where it began its circuit of the body there is no to-and-fro movement of blood in the veins, but a constant flow of blood to the heart.

The next estimate he used was that the heart beats 1, times every half an hour, which gave 10 pounds 6 ounces of blood in a half an hour, and when this number was multiplied by 48 half hours in a day he realized that the liver would have to produce pounds of blood in a day, more than the weight of the whole body.

He compared the ileocecal valve to the venous valves, and not vice-versa. Born in Folkestone, England, William Harvey studied at Cambridge and then spent several years at Padua, where he came under the influence of Fabricius. Harvey may have learned of this similarity from Fabricius.

He also artfully illustrated the workings of the valves in veins, proving the one-way circulation of venous blood towards the heart, and refuting the notion that the valves were actually reinforcement structures that prevented the over expansion of the veins as blood was forced through, as his university mentor Girolamo Fabrici had taught.

Finally he deals with embryogenesis in viviparous animals especially hinds and does.

William Harvey and the Discovery of the Human Circulatory SystemOverviewWilliam Harvey () is recognized as the man who discovered and published the first accurate description of the human circulatory system, revolutionary theory of the physiology of blood circulation.

William Harvey made the momentous medical discovery that the flow of blood must be continuous and that its flow must be in one direction only. This discovery sealed his place in the history of medicine. Sep 21,  · Harvey's predecessors and contemporaries believed the blood to be continually formed anew from the digested food, to be dissipated and used up in the tissues, and considered that the primary function of the heart was the production of heat.

Subject Matter: The discovery of blood circulation in the human body and the development of the theory.
