William Harvey Theory: Heart Pump Blood Through The Whole Body

In document seven, William Harvey discusses the blood flow of the human heart and compares it to that of the flow of the government. While the document is most likely propaganda to flatter King Charles of England, it does present a fairly accurate description of the blood flow which would not have been possible without scientific discoveries caused by the invention of the printing

He soon created the condition in animals, so that he work on treating it. At last he discovered a new pathway to the heart. Not too soon after a young girl named Eileen Saxon, who was close to death, was rushed into John Hopkins to try this new solution. Although Thomas had done this surgery correctly countess times it was still Blalock (who had preformed the entire surgery by him self once) who preformed the surgery. In the article it states, “Each time the surgeon was ready to make a cut or stitch into Eileen’s tiny chest, he would listen for Thomas’s instructions.” Eileen became the first human to have a successful open heart surgery. Even though Thomas made the discovery, Blalock received all of the credit from the

William Harvey, Physician to King James and Charles I, was the first person to correctly describe the full circulation of blood in human and animals. This was his greatest contribution to the scientific world, because prior to his discoveries and theories, not much was known about the heart and its role in blood circulation. Harvey was also one of the first people to suggest that humans and other mammals reproduced through the fertilization of an egg cell and a sperm cell.

Experimental evidence is necessary to prove your findings, especially in today’s society. Harvey pushed the limits of science by extensively studying veins and arteries, and by performing vivisections. Harvey was able to use his observations and evidence to determine the full circulation of blood in the human body. Unlike Harvey many scientists were apprehensive about experimental science perhaps this was due to their religion or beliefs. Harvey mentioned many scientists weren’t willing to learn and based their findings on Galen and his teachings. Scientist were not willing to step out of the box to discover the unknown. Harvey was definitely ahead of his time. it is interesting how accurate Harvey was compared to today's science.

Due to Hofmann’s accomplishments, he conceitedly questioned Harvey’s result which was done using arithmetic; leaving Harvey humiliated. Formerly, arithmetic was not a basis in finding causes of a phenomenon in anatomy or philosophy, and it was not considered to be academically important. Therefore, Harvey’s theory was considered insupportable. Moreover, Hofmann believed that Nature was perfect, and used that belief as a basis to question the purpose of Harvey’s theory. Hofmann believed that Nature was not absurd to create more blood than needed by the body just to contaminate it and reuse it.

According to the news, people who hope to drive New York City's famous yellow cabs no longer have to take an English language proficiency test. In other words, NYC eliminates an English test for yellow cab drivers under new rules designed to make it easier for immigrants to get behind the wheel of a yellow cab. The test for a taxi licence will be available in several languages under regulations that went into effect three weeks ago. So that means I can become a yellow cab driver, too.

Physics is known to be a natural science. It majorly entails the study of matter and the motion of matter through time and space, along with related concepts such as force and energy. Does the circulatory system apply concepts in physics as the blood circulates through the entire system? The circulatory system’s main objective is to transport blood throughout all the necessary parts of the body. The blood in effect transports nutrients and oxygen to these body parts and wastes away from these body parts to the organs that excrete them out of the body. The heart is the nerve centre of the circulatory system. This is so as it is this organ that pumps the blood that carries both the nutrients and wastes to the appropriate parts of the body.

Through his investigation founded on beliefs of Aristotle, William Harvey was able to hypothesize on the movement of blood in the body. Prior to William Harvey’s research , the medical view of blood in the body came from a Greek doctor by the name of Galen. Galen explained the flow of blood as a to-and-fro movement being pumped by the veins and arteries themselves. Galen also believed that blood was made and then used up in the body. His conclusions were drawn mainly from outer appearances (Bayon 444). This made Harvey’s work more accurate because he performed specific experiments and calculations. One reason Harvey was able to determine the movement of blood through the body was founded in Aristotle’s belief of the perfection of circular motion because it is continuous path (Pagel 28). William Harvey combined this idea with Arsitotle’s view of the power of the heart to act independently of the brain. From these notions, Harvey created the theory of a constant circulation of blood throughout the body by the pumping of the heart. He began researching his hypothesis with a hen’s egg. He discovered that the first drops of blood in the hen’s egg eventually gave

Every so often Seymour would pass through a valve, a mysterious doorway of sorts that some atoms quite feared. It gave many the eerie “you can never go back” feeling that a haunted house would. Seymour saw them as more of a welcoming, like the doors to Jurassic Park, as they were being brought to something grand and wouldn’t even think of turning back. The final Jurassic Park door led to the main road, the inferior vena cava. Here countless number of veins converged all to go to the heart. Here was where the serenity ended, and the incessant noise of the Heart & Lung Univerity began.

Biological principles were heavily influenced by Aristotle. William Harvey, the founder of modern physiology was strongly influenced by Aristotle and "... founded much of his work on the Aristotelian assumption that the shape, structure and size of each organ in the body the animal indicated its purpose and function of the entire system. "7 The idea of ​​spontaneous generation was a commonly held belief, with roots back to Aristotle8 and was not disproved until experiments were conducted by Louis Pasteur.9
