William Harvey: The Discoverer Of The Blood And Heart System

The purpose of this paper is to compare and contrast how a toxin will affect the systems in the

“Galen’s work set the stage for William Harvey’s first description of the circulatory system and thereafter the function of the heart”

I selected Dr. Richard Sowers, a prinicipal investigator and oncologist. He is head over a research team that has published over 50 publications and discovered many advances in medicine. Dr. Sowers describes his role as the need to better and advance medicine, in order to do so, some people have stated that he was ‘mean’ and ‘arrogant’. Dr. Sowers is not concerned of how his employee’s view him as he is only there for one thing, caring for his patients while discovering new health care advancements. Dr. Sowers life status is a respected researcher and physician.

The case I found more compelling was the case of Huang Xian. His case was shocking, he did not he had his body that bad. He had broken veins, broken bones of his hand and he had wounds on his body. If it had not been for the doctor that orders him a checkup he had not known how bad his health and his body were. I was compassionate about his case and how much he suffers. One of the things that save him during he was a prisoner was writing poems to his wife.

Belgrave/Dr. Burke (?) | There must be a workaround because Dr. Belgrave/Dr. Burke had cases at St. Francis that he would retrospectively deny the observation and St. Francis would request to cover as in-patients.

Sir Alexander Fleming was one of the most important scientists of all time leading a breakthrough in medicine. Correspondingly, Sir Alexander Fleming changed the way that medicine would be used forever with his accidental findings of lysozyme and the first antibiotic. This discovery led to lives being saved from bacteria and the battle against harmful bacteria.

Cardiovascular system is powered by the body’s hardest-working organ the heart, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 litres of blood throughout the body every minute. The cardio vascular system delivers oxygen to the body tissues from the lungs and nutrients to the liver from the intestines. The cardiovascular system also removes carbon dioxide from the cells to the lungs, to be excreted and also removes waste products from the liver to the kidneys. The cardiovascular system transports white blood cells, Antibodies and hormones to different parts of the body.

The cardiovascular system consists of the heart, which is a muscular pumping device, and vessels called arteries, veins, and capillaries (Silverthorn, D.U, et al. 2016). The heart pumps blood around a closed unit of vessels as it passes through circulations of the body.

The cardiovascular system is also known as the circulatory system, which is an organ system that encompasses the heart and blood vessels of the body. The heart and blood vessels of the circulatory system adapt to repeated sessions of exercise in number of ways, the cardiovascular system carries blood, oxygen and nutrients to the organs and tissues of the body and carries waste products and carbon dioxide from these tissues to be removed from the body.

“Homeostasis comprises the dynamic processes that enable optimum conditions to be maintained for cells, in spite of continual changes taking place internally and externally” (Doherthy & Foudy, 2006, p. 26). I chose the cardiovascular system based on the fact that blood has to circulate to all of the other systems to help keep tissues and organs functioning. The organ of the cardiovascular system is the heart and the system also has arteries veins, and capillaries which are the blood vessels. The main tissues that are in the cardiovascular system are the epithelial tissue, muscle tissue, nervous tissue, and connective tissue. The cells that are associated with this system are red blood cells, white blood cells, platelets and then plasma a

addition, this article makes us to understand that the circulatory system comprises of various organs and vessels which plays a pivotal role in the flow of blood, hormones, nutrients, oxygen as well as gases that enters and leave the cells. More so, this article also bring to our awareness the fact that, the circulatory system comprises of three separate or independent systems that work together. These three independent systems consist of the heart ( cardiovascular), the lungs (pulmonary) and arteries, veins, coronary and portal vessels. With the cardiovascular component consisting of the heart, blood as well as blood vessels. In addition, it has a lop through the lungs whereby, blood is been oxygenated. Furthermore, the systemic circulation is also incorporated and runs through the rest of the human body in order to provide oxygenated blood. More so, this article brings to our awareness the fact that oxygen depleted blood is been send away

Alexander Fleming made amazing discoveries that changed medicine back when it was only used in war. His first discovery

The first accurate recording using an electrocardiogram (ECG) occurred in 1895. Willem Einthoven was the first person to create an ECG that accurately depicted the recording of the heart’s electrical currents (Jenkins, 2011). Einthoven “was awarded the Nobel prize in Physiology or Medicine”(Nobelprize, 2014, p. 1) in 1924 for the discovery of the electrocardiogram (Nobelprize 2014). Not only did he configure the machine but he also created the deflections. They are the labels of the points on the wave created by the electrocardiogram, PQRST, are the letters at each point or curve on the wave . Einthoven was the sole founder of the ECG but without the help of previous scientist Einthoven would have never discovered the electrocardiogram

I am Curtis the scientist I pick for my Writing frame is William Harvey.His theory was heart pump blood through the whole body.William Harvey is correct and why he is correct.

As the world of technology changes, we get to explore and visually get to see how the heart and the Circulatory system works. “The cardiovascular system consists of the heart and blood vessels circulating blood throughout the body, delivering water, oxygen, and nutrients to cells, and removing waste products such as carbon dioxide blood vessels working together to is system”. (Wiley) And now for the Circulatory system is also a major function of our body, “The basic circulatory system of vertebrate animals, which are those with a backbone, consists of a heart, the blood and the arteries and system of blood vessels. The heart pumps the blood first to the arteries and then throughout the body via the system of blood vessels”. (reference.com)
