William Harvey, a man who was born in Folkestone, England in April of 1578, grew up to be a scientist that began his career researching about the Circulatory System, and how blood was transported throughout the body. The circulatory system is defined as: “an organ system that permits blood to circulate and transport nutrients.” Harvey was known as “the Father of Modern Physiology.” He earned his bachelor’s degree from the University of Cambridge, and his doctorate in medicine in 1602 from the University of Padua (Ballaro 1). After Harvey graduated, he packed his bags and went back to England and set up his own medical practice. In the year of 1607, Harvey was invited to join the Royal College of Physicians, and nearly two years later was appointed …show more content…
Galen was a Greek physician and scientist who studied the circulatory system and how blood flow worked; his research persuaded people that lungs were the main source of blood flow in the body. He was born in AD 129 and died in AD 217. Other physicians during Harvey’s time of research had thought that the lungs were the source of blood flow throughout the body. Standard citizens did not know what to think or who to believe when it came down to the circulatory system, but Harvey had done a lot of research and tests trying to prove that the lungs were not as important as other physicians and scientists said they were. Harvey published his findings in the book Anatomical Studies on the Motion of the Heart and Blood in Animals, in 1628. Harvey’s peers did not respect his work in this field. It was another fifty years after Harvey’s death that his work was fully appreciated and accepted. Since the time of Harvey and Galen, surgeons and scientists today can thoroughly track the flow of blood in the standard circulatory system (Lauer 1). Although Harvey did not win any awards for his outstanding research, there is an award named after him that describes what he did during his lifetime and how he proved that the blood flow in the circulatory system does not depend on the lungs.
Freedom of Speech is a fundamental right that makes America the “land of the free.” But this right is abused by many people, and Philip Malloy is one of those individuals. Philip Malloy’s First Amendment Rights regarding his Freedom of Speech were not violated because there was a rule that he was informed about multiple times, but he still disrespected it.
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
Furthermore, Aristotle and Galen’s theories contributed to the Renaissance revival of heart anatomy. This reawakening made it possible for physicians to indicate the basic arrangement of the heart. It became commonly accepted that the heart was divided into four parts: two ventricles (lower chambers that pump blood out) and two auricles (upper chamber that r...
“Whenever my environment had failed to support or nourish me, I had clutched at books...” ― Richard Wright, Black Boy this is a quote from the famous Richard Wright an African American author. This quote means that no matter what was placed in his way or what he lacked that others had he hung on to what he had and did what he could. And the more he read about the world, the more he longed to see it and make a permanent break from the Jim Crow South. "I want my life to count for something," he told a friend. Richard Wright wanted to make a difference in the world and a difference he did make. Richard Wright was an important figure in American History because he stood astride the midsection of his time period as a battering ram, paving the way for many black writers who followed him, these writers were Ralph Ellison, Chester Himes, James Baldwin, Gwendolyn Brooks, Lorraine Hansberry, John Williams. In some ways he helped change the American society.
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).
Poet, journalist, essayist, and novelist Richard Wright developed from an uneducated Southerner to one of the most cosmopolitan, politically active writers in American literature. In many of Richard Wright's works, he exemplifies his own life and proves to “white” America that African American literature should be taken seriously. Before Wright, “white” America failed to acknowledge the role African American writing played in shaping American culture. It was shocking in itself that an African American could write at all. Thus, Richard Wright is well known as the father of African American literature mainly because of his ability to challenge the literary stereotypes given to African Americans.

William Caslon, also known as William Caslon the Elder, was born in Cradley, Worcestershire England, The exact date is unknown but it is speculated to be in the years 1692 or 1693. About the age of seventeen he started as an apprentice engraving gunlocks and gun barrels in London. Engraving was a historically important method of producing images on paper in artistic printmaking. Ten years after that Caslon opened up his own engraving shop in 1716 in London and he began to create tools for bookbinders and silver objects. During this time Caslon’s work took the attention of the printer John Watts and many other presses in London. These companies asked Caslon for his work, by making cutting type punches. “In 1720 Caslon designed ”English Arabic” typeface used in psalter and a New Testament.” Stated by the Editors of Encyclopedia Britannica) . Then later in time he worked in cutting roman, italic, and Hebrew typefaces for William Bowyer. In so doing he created the Roman typeface, which was first, used in 1726. It was renamed Caslon.
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...
Deemed one of the most popular British graphic designs of his generation, Peter Saville, born on October 9th, 1955 started his designer career with study at Manchester Polytechnic in graphic designing. Saville’s fame rose 1978 after meeting journalist and record label owner, Tony Wilson, whom commissioned Saville to design posters for the label. Saville design’s were recycled and appropriations of images from earlier in history with a retrospective impression, this was a type of finger print to Saville’s work - making it unique and visibly his work. Saville used re-creations of an earlier to resemble codes to symbolise an attitude and/or position on a item or issue, depending on the circumstances of the commission of initial intent of the

Briefly explain how Hitchcock blended genres. -Hitchcock blended action and drama for North by Northwest. You know it’s an action film because Roger Thornhill is the “good guy” that you root for against Vandamm in the film. However, by adding Roger’s love interest Eve Campbell, drama is also introduced in the film. Throughout the film, after Roger meets Eve, the plot has a focus concerning their relationship to one another and its development.
Hippocrates, often called the “father of medicine” was one of the earliest contributors to modern science. He was called the father of medicine because through his medical school, he separated medical knowledge and practice from myth and superstition basing them instead of fact, observation, and clinical ...
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.
