Our medical advancements are the gramercy of the renowned British physician, William Harvey, who accurately described how blood circulates throughout the body, how animals develop, and set a basis for the scientific method. Harvey was born in 1578 in Folkestone, England. He attended Caius College, Cambridge, where he studied the classics, rhetoric, and physiology, and he finished with a Bachelor of Arts degree. Afterwards, he moved to the University of Padua in Italy, the greatest medical school at the time, and he earned a doctorate degree (Aird). He studied under Hieronymus Fabricius and adopted Aristotle’s methods of the study of nature, mostly in comparative anatomy and embryology, and began to challenge Galen’s ideas which were the widely …show more content…
This created a new field of research, known as physiology, because people wanted to have a better understanding of the human body, especially the heart. In 1628, he made his research public by writing a book: Exercitatio anatomica de motu cordis et sanguinis in animalibus which translates to An Anatomical Essay Concerning the Movement of the Heart and Blood in Animals (“About William Harvey”). He became interested in blood and conducted an experiment where blood from the vein and blood from the artery were both extracted and placed in a basin. He learned that it was “the same blood in the arteries as in the veins, after having tied them in the same way, as [he] repeatedly ascertained… [people] may fairly conclude that the arteries contain the same blood as veins, and nothing but the same blood” (Harvey 12). They were even the same color, of the same consistency, and the same volume (Aird). This contradicted Galen’s idea that veins contain blood and arteries contain blood and spirits (Aird). He used this exact same experiment to confute Jean Roinlan, a French doctor who published a book disproving some of Harvey’s ideas (Yount 86). Harvey’s ideas changed the way scientists think about the circulatory system. They know now that it works as a system of veins and arteries since they carry the same blood. Although Harvey did not know why the blood was two different colors, scientists have performed more tests over the years and now know it is because one has oxygen and the other one does
In 1615 at the age of 37 Harvey became the Lumleian Lecture specializing in Surgery. William Harvey discovered his finding of the Circulation of Blood by ignoring medical textbooks and dissecting animals. He gained all or most of his learnings from observations of cutting open veins and arteries of living animals. Many people of this modern time thought because there weren’t any anesthetics that Harvey was cruel for cutting open living animals. I think that if it wasn’t for William Harvey and all of his studies and dissections that we wouldn’t be able to learn teach and save as many people as we can today. We as people have learned a lot from the many studies and dissections throughout Harvey’s lifetime. We have learned that blood, arteries, and veins are all within the same origin, blood in the arteries sent to the tissues are not stay there, the body‘s circulation mechanism was designed for the movement of liquid and that blood carrying air is still blood, the heart moves all movements of blood not the liver, hearts contract the same time as the pulse is felt, ventricle’s squeeze blood into main arteries, the pulse is formed by blood being pushed into arteries making them bigger, there are no vessels in the heart’s septum, lastly there is no to in from of blood in the veins there is only

The Mayo Clinic’s book on High Blood Pressure was full of detailed facts about blood pressure and what it is. This is extremely significant to the experiment because blood pressure is one of the variables being tested. Understanding blood pressure is one of the key components to receiving accurate results from this experiment. Most of the book is on high blood pressure, which is not necessary for the experiment, but the book still had plenty of useful information about blood pressure itself. The book explains that when the heart beats, a surge of blood is released from the left ventricle. It also tells of how arteries are blood vessels that move nutrients and oxygenated blood from the heart to the body’s tissues. The aorta, or the largest artery in the heart, is connected to the left ventricle and is the main place for blood to leave the heart as the aorta branches off into many different smaller
William Clark was ½ of the genius team that made their way through miles of unknown land, unknown nature, unknown natives, and came home with all but one voyager, who was killed of natural causes. William Clark and Meriwether Lewis were the first Americans to try and map the Louisiana Purchase area, and not only did they map it, they discovered allies, new plants and animals, and discovered new land and water routes that could be useful for future travelers.
Many of the subject’s were twins, mostly identical. Twins when through the worst of the surgeries, including blood transfusions. Doctors drained one twin of his blood and inject it into the other twin to see what would happen. Blood would be drawn from each twin in large quantities about ten cubic centimeters were drawn daily. The twins who were very young suffered the worst of the blood drawing. They would be forced to have blood drawn from their necks a very painful method. Other methods included from their fingers for smaller amounts, and arms sometimes from both simultaneously. The doctors would sometimes see how much they could withdraw until the patient passed out or died.
The science and history of the heart can be traced back as far as the fourth century B.C. Greek philosopher, Aristotle, declared the heart to be the most vital organ in the body based on observations of chick embryos. In the second century A.D, similar ideas were later reestablished in a piece written by Galen called On the Usefulness of the Parts of the Body. Galen’s thesis was that the heart was the source of the body’s essential heat and most closely related to the soul. Galen made careful observations of the physical properties of the heart as well. He said “The heart is a hard flesh, not easily injured. In hardness, tension, in general strength, and resistance to injury, the fibers of the heart far surpasses all others, for no other instrument performs such continues, hard work as the heart”(Galen, Volume 1).
The only surgeon was one who combined the occasional exercise of that noble art with the daily and habitual flourish of a razor. To such a professional body Roger Chillingworth was a brilliant inquisitor. He soon manifested his familiarity with the ponderous and imposing machinery of antique physique; in which every remedy contained in multitude a far fetched and heterogeneous ingredients […] He had gained much knowledge of the properties of native herbs and roots(Hawthorne 108-109).
...iments opened the flood gates for anatomical and physiological observation. And his observations in regards to blood were so close to uncovering the true nature of circulation that William Harvey wondered how Galen himself did not arrive at the conclusion (Klein, 2009). Galen set an important foundation for future physicians.
The blood transfusions started out as an already dangerous procedure during its early stages. Not only were the obvious factors of cleanliness and bacteria control an issue, but the question of blood types had yet to be raised. Despite this, some early blood transfusions were successful, such as Jean-Baptiste Denys’s transfusion of lamb’s blood into an adolescent suffering from fever in 1667. Nonetheless, many early transfusions were fatal, thus research on this procedure was halted until the nineteenth century. This research began to provide tangible hope in 1901 when the first blood group (ABO) was identified by Karl Landsteiner. This discovery explained the deaths of patients who had received an incompatible blood type. Further triumphs in medicine were achieved, such as the use of sodium citrate as an anti-coagulant and increased measures to create sanitarAs these improvements surfaced over the course of the first half of the twentieth century, the general population of the 1960s saw blood transf...
More medical discoveries and advances are occurring every day. Medical treatments and understanding of the human anatomy have come a long way. Though if it weren’t for certain Anatomists, we may have not have had the right comprehension of the human body which could have led to errors in surgery and more deaths while treating patients. The Renaissance period was a time where Anatomists searched for clearer understanding of the human body. During the Renaissance period, Anatomists questioning and experimentation led to great discoveries of the human body.
William Harvey was born on April 1, 1578, in Folkestone, England. At the age of sixteen, Harvey enrolled in Gonville and Caius College in Cambridge where he obtained a bachelor's degree in 1597. He went on to study medicine under Hieronymus Fabricius at the University of Padua in Italy. Fabricius was involved in the study of blood flow in the body, which motivated Harvey to research this branch as well. After moving to England, William Harvey was appointed as a personal physician to King Charles (Britannica). Within his study of blood, Harvey was able to form the theory of the circulation of blood through the body, which he published in ‘On the Motion of the Heart and Blood in Animals', in 1628. The book brought Harvey fame and made him a respected name in science. During his experiments, William Harvey became skeptical of pr...

Through the use of the microscope and the discovery of DNA, there were many advances in anatomy and physiology throughout the twentieth century to the present time. However, the early discoveries by Erasistratus and Herophilus as well as the others created a foundation for the future scientists to base their research off of, which impacted where we are today in the field and contributed to the great advances that have been made in anatomy and physiology.
William Bateson has made numerous contributions to the fields of genetics and evolution over these past few decades that have changed the concept of both disciplines. Bateson is largely responsible for bringing Mendelian genetics back to life and solidifying its characteristics as the basis for inheritance. Without the contributions of Bateson, society would not have learned the importance of experimental methodology in genetics. Bateson has proved his worth via his ground breaking research, his membership to the Royal Society of London along with the accolades of the Darwin Medal in 1904 and the Royal Medal in 1920. Bateson has spent a tremendous amount of time in the field and academia performing ground breaking research.
