The discoverer of the circulation of the blood, was born at Folkstone, in Kent, on the 1st of April 1578. The heart’s regular contractions drive the flow of blood around the whole body. Definition However, the date of retrieval is often important. At the time, reproduction was poorly understood, and Harvey investigated issues of the role of sperm and menstrual blood in the formation of the embryo. Thus, its discovery – a turning point in the annals of biomedical history – depended on inference through clever experimental approaches, as pioneered by William Harvey.

However, there is a need for considerable caution here. William Harvey discovered the principle of the circulation of the blood through the body. He concluded that the active phase of the heartbeat, when the muscles contract, is when the heart decreases its internal volume and that blood is expelled with considerable force from the heart. William Harvey’s discoveries and their eventual acceptance meant that medical practises in general improved greatly during the end of the renaissance period and beyond. Harvey would not attempt to answer why the blood traveled to the lungs and back, as he did not have any knowledge about gas exchange during pulmonary respiration. A short video about William Harvey, an English physician who made seminal contributions in anatomy and physiology. His great achievement was the demonstration of the circulation of the blood, a discovery which replaced centuries of theory and speculation with knowledge firmly based on accurate observation and experiment. His still impressive research is also seen as the first milestone of modern experimental science, and can be used as an example of how to perform experimental scientific research. William Harvey (1578-1657) is recognized as the man who discovered and published the first accurate description of the human circulatory system, based on his many years of experiments and observations as a scientist and physician. . These were actually quite ancient ideas and notions, still accepted more than 1,400 years after first being postulated by Galen (130?-200? Refer to each style’s convention regarding the best way to format page numbers and retrieval dates. 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 (1537-1619) had taught. Harvey concluded that blood moved from the right ventricle into the lungs via the renamed pulmonary artery (correctly changed from pulmonary vein), which Galen thought carried only air and "soot" back and forth between the lungs and heart. Demographics The first ones were registered in the middle of s. XVII. He made estimates of the volume of the ventricles, how efficient they were in expelling blood, and the number of beats per minute made by the heart. This discovery became a key turning point in Harvey’s life, because it inspired him to investigate the function of these valves, and in doing so, to discover the circulation. The growing skepticism of Galen’s work had a great influence on William Harvey, who was born in Folkestone, England, in 1578. Harvey claimed he was led to his discovery of the circulation by consideration of the venous valves. Harvey had accumulated a mass of irrefutable experimental evidence in support of his dramatic new view, knowing that a tremendous amount of criticism and disbelief would be mounted against his groundbreaking, revolutionary theory of the physiology of blood circulation.

According to Galenic doctrine, the liver was seen as the continual source of new blood, replenishing the blood that was vaporized and converted into waste material, and released from the lungs as "soot.".

This "venous blood" then entered the hepatic vein, which he believed to be the origin of the vena cava, and the "descending" vena cava transported blood to the lower body, while the "ascending" branch sent blood to the upper body.
