Galen was a Roman doctor who gained knowledge through animal dissections. He understood the importance of the pulse and that blood moved around the body, but he made some mistakes. For example, he thought that the liver made blood for the veins and the heart made blood for the arteries
Sigmund Freud was born May 6, 1856, in Freiberg, Moravia (now Czechoslovakia), and died September 23, 1939, in exile in London. When the boy was three, his father, a small wool merchant, was forced by economic reverses to move for a year to Leipzig and thence to Vienna, where Freud spent the rest of his life—1860 to 1938— except for his last year. His biographers agree that the unusual structure of the family into which he was born was partly responsible for his interest in intimate human relationships: Freud’s father had two sons by his first wife; when he remarried after her death, it was to a woman of their age. Sig mund, her first child, often played with his year-older nephew. A brother who was born when Sigmund was not yet a year old died after eight months; then came four sisters and another brother.
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. 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. Although the majority of the physicians and scientists of his day refused to accept his research, Harvey's discovery and written description of the true functioning of the heart and circulatory system remains as one of the landmark medical textbooks and the foundation of modern physiology.
Harvey's great contribution to medicine was his revolutionary discovery of the circulation of blood. By dissecting both living and dead animals, Harvey became convinced that the ancient Greek anatomist Galen's ideas about blood movement must be wrong, particularly the ideas that blood was formed in the liver and absorbed by the body, and that blood flowed through the septum (dividing wall) of the heart. Harvey first studied the heartbeat, establishing the existence of the pulmonary (heart-lung-heart) circulation process and noting the one-way flow of blood. When he also realized how much blood was pumped by the heart, he realized there must be a constant amount of blood flowing through the arteries and returning through the veins of the heart, a continuing circular flow.
Galen's understanding of anatomy and medicine was principally influenced by the then-current theory of humorism, as advanced by ancient Greek physicians such as Hippocrates. His theories dominated and influenced Western medical science for more than 1,300 years. His anatomical reports, based mainly on dissection of monkeys, especially the Barbary Macaque, and pigs, remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius[10][11] where Galen's physiological theory was accommodated to these new observations.[12] Galen's theory of the physiology of the circulatory system endured until 1628, when William Harvey published his treatise entitled De motu cordis, in which he established that blood circulates, with the heart acting as a pump.[13][14] Medical students continued to study Galen's writings until well into the 19th century.

Harvey, observing the notion of the heart in living animals, was able to see that systole was the active phase of the heart's movement, pumping out the blood by its muscular contraction. Having perceived that the quantity of blood issuing from the heart in any given time was too much to be absorbed by the tissues, he was able to show that the valves in the veins permit the blood to flow only in the direction of the heart and to prove that the blood circulated around the body and returned to the heart. Fabricius, his teacher in Padua, had discovered the valves in the veins.

The Framingham Heart Study is a long-term, ongoing cardiovascular study on residents of the town of Framingham, Massachusetts. The study began in 1948 with 5,209 adult subjects from Framingham, and is now on its third generation of participants.[1] Prior to it almost nothing was known about the "epidemiology of hypertensive or arteriosclerotic cardiovascular disease".[2] Much of the now-common knowledge concerning heart disease, such as the effects of diet, exercise, and common medications such as aspirin, is based on this longitudinal study. It is a project of the National Heart, Lung, and Blood Institute, in collaboration with (since 1971) Boston University.[1] Various health professionals from the hospitals and universities of Greater Boston staff the project.
William Harvey was born in 1578 in Folkstone, England. The eldest of seven sons, Harvey received a Bachelor of Arts degree from Cambridge in 1597. He then studied medicine at the University of Padua, receiving his doctorate in 1602. By all measures, Harvey was successful. After he finished his studies at Padua, he returned to England and set up practice. He then married Elizabeth Brown, daughter of the court physician to Queen Elizabeth I and King James I. This put in him in position to be noticed by the aristocracy, and Harvey quickly moved up the ladder. Eventually, he became court physician to both King James I and King Charles I.

But more about that later.
Because of his family status, Harvey had no problem obtaining a privileged education. He studied at the elite King’s School in Canterbury (1588–1594) and later at Gonville and Caius College of Cambridge University, where he received a B.A. He obtained a Doctor of Physic diploma from the University of Padua in 1602. That institution, the alma mater of the same Dr. Caius who helped found Harvey’s alma mater at Cambridge, was one of the great centers of medical education at the time, the home of Galileo and the great anatomist Versalius. There Harvey studied under a student of Versalius, Fabricius, who had written a treatise on the valves in veins but hadn’t the vaguest idea about what they did other than that they might slow blood flow (6,13,14,17).
Years later, when Harvey was close to death, he was asked by Robert Boyle what had induced him to think that the blood circulated (13,17). Harvey replied
...that when he took notice the Valves in the Veins of so many several parts of the body, were so plac’d that they gave free passage to the Blood Towards the Heart, but oppos’d the passage of the Venal blood the Contrary way: He was invited to imagine that so Provident a Cause as Nature had not so Plac’d so many Valves without Design: and no Design seem’d more probable, than That, since the Blood could not well, because of the interposing Valves, be Sent by the Veins to the Limbs; it should be Sent through the Arteries and Return though the Veins, whose Valves did not oppose its course that way. (4)
After returning to London, Harvey obtained his M.D. degree from Cambridge (1602); he became a Fellow of the Royal College of Physicians in 1607 and the physician to St. Bartholomew’s Hospital in London in 1609. Later, at the age of 37, he was appointed to the distinguished position of Lumleian Lecturer in anatomy at the College of Physicians. It was in the latter capacity that he undertook the experiments that were to lead to one of the greatest scientific revolutions of the century — one that was to abolish, without a trace, a dogma that had persisted for almost 1,500 years (11,12,14).

Christian Barnard’s place in medial history is based on the fact that Barnard performed the first open heart transplant in history. In 2002 such operations are common but in the late 1960’s operations on the heart were rarely performed because of the risk of death and heart transplants were unheard of. my site is http://www.historylearningsite.co.uk/christian_barnard.htm

...that when he took notice the Valves in the Veins of so many several parts of the body, were so plac’d that they gave free passage to the Blood Towards the Heart, but oppos’d the passage of the Venal blood the Contrary way: He was invited to imagine that so Provident a Cause as Nature had not so Plac’d so many Valves without Design: and no Design seem’d more probable, than That, since the Blood could not well, because of the interposing Valves, be Sent by the Veins to the Limbs; it should be Sent through the Arteries and Return though the Veins, whose Valves did not oppose its course that way. (4)
After returning to London, Harvey obtained his M.D. degree from Cambridge (1602); he became a Fellow of the Royal College of Physicians in 1607 and the physician to St. Bartholomew’s Hospital in London in 1609. Later, at the age of 37, he was appointed to the distinguished position of Lumleian Lecturer in anatomy at the College of Physicians. It was in the latter capacity that he undertook the experiments that were to lead to one of the greatest scientific revolutions of the century — one that was to abolish, without a trace, a dogma that had persisted for almost 1,500 years (11,12,14).
Fabricius discovered veins.

Christian Barnard performed the first human-to-human heart transplant
ReplyDeleteIn 1929, German surgeon Werner Forssmann (1904-1979) examined the inside of his own heart by threading a catheter into his arm vein and pushing it 20 inches and into his heart, inventing cardiac catheterization, a now common procedure.

Christian Barnard’s place in medial history is based on the fact that Barnard performed the first open heart transplant in history. In 2002 such operations are common but in the late 1960’s operations on the heart were rarely performed because of the risk of death and heart transplants were unheard of. my site is http://www.historylearningsite.co.uk/christian_barnard.htm

Galen was a Roman doctor who gained knowledge through animal dissections. He understood the importance of the pulse and that blood moved around the body, but he made some mistakes. For example, he thought that the liver made blood for the veins and the heart made blood for the arteries. http://www.bbc.co.uk/schools/gcsebitesize/science/triple_ocr_gateway/the_living_body/circulatory_systems_cardiac/revision/5/
ReplyDeleteWilliam Harvey was born in 1578 in Folkstone, England. The eldest of seven sons, Harvey received a Bachelor of Arts degree from Cambridge in 1597. He then studied medicine at the University of Padua, receiving his doctorate in 1602. By all measures, Harvey was successful. After he finished his studies at Padua, he returned to England and set up practice.

William Harvey (1578-1657), the father of modern physiology, was the first researcher to discovery the circulation of blood through the body.

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. 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. Although the majority of the physicians and scientists of his day refused to accept his research, Harvey's discovery and written description of the true functioning of the heart and circulatory system remains as one of the landmark medical textbooks and the foundation of modern physiology.
