A Life In Circulation Summary

Wilhelm Maximilian Wundt was born on August 16th in 1832. He was born in the town of Neckarau in Germany to a Lutheran minister. He was an intelligent, odd boy, taught mostly by his father’s associate, Friedrich M üller, whom he moved in with later on. Wundt studied at the Gymnasien and then at the University of Tübingen in 1851, when he was 19 years old. He transferred after only one year to the University of Heidelberg, majoring in medicine. He published his first publication during his third year there. He changed his major from medicine to physiology, studying under Johannes Müller at Berlin for a semester. Wundt received his doctorate in medicine at Heidelberg, and worked as Hermann von Helmholtz’s assistant 2 years afterwards for 7 years.

William Harvey published the book called “An Anatomical Account of the Motion of the Heart and Blood in Animals” which was officially published a fair time after the other two’s books. He proved that the heart acts as a pump by recirculating the blood, and showed that the blood flows around the body and is carried away by the arteries and is carried back into the heart by the veins. This had a limited impact because likewise to Vesalius, it did not make anyone healthier at the time, and it made more of a long term impact on medicine. He had not found a way to practically cure people because he had just made a book to further people’s knowledge on how the body works. Although his book is very useful for us nowadays, at the time people would not know how to approach it, and really wouldn’t make much of an impact on the people’s health.

A revolution in medicine began in the 16th century. During this time Andreas Vesalius and William Harvey added to the understanding of human anatomy. By dissecting human bodies at the University of Padua, Vesalius described the individual organs and general structure

William Harvey studied the heart along with the circulation of blood and discovered that the information taught about the cardiac system was incorrect. In the late 1500’s and the early 1600’s, it was unheard of to practice anatomy, for example operating on the deceased. Harvey desired to know more and he discovered,“...when we see that with excessive repletion the pulse bats more forcibly, whilst the respiration is diminished in amount…”(citation). People at the time thought the pulse of the heart and respiration were the same, but with the research Harvey conducted he proved this theory wrong. The pulse

Almost 80% of people die from heart disease. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. Once you know your overall risk, agree with your healthcare professional on a plan for specific actions you should take to reduce your risk for heart disease and stroke. The Circulatory System is made up of three main parts: The heart, the blood vessels and the blood. Sometimes the watery fluid called lymph and the vessels that carry it are considered to be part of the Circulatory System. The heart is a special pump that pumps the blood around the body. The purpose of this paper was to summarize information about the heart, explain how it works, and discuss its purpose. It was said that the heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, than a snake's, with three, before finally adopting the four-chambered structure of the human heart. I also told you how the heart works. When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart. Now the purpose of the heart is the size of its owner's clenched fist, the organ sits in the middle of the chest, behind 1the breastbone and between the lungs, in a moistened chamber that is protected all round by the rib cage. It can also be easy to fix the heart. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. The heart is very important for your

Another important person in comparative anatomy was William Harvey, an English physician. He was the first to describe completely and in great detail the systemic circulation and properties of blood being pumped to the brain and body by the heart. In Harvey’s view, the heart is the foundation of human life, “upon which, all growth depends,

One of these was Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus which translates to On the Motion of the Heart and Blood in Animals. He first published it in Frankfurt, 1628 while he was a lecturer at the Royal College of Physicians. It is believed that there was no original copy of the book as it was produced through mass production and so many copies exist in museums today. However, a copy of the original title page of the book is held in the Science Museum, London. William Harvey's book on wasn't specifically created for someone. Instead, curiosity about the body resulted in him recording his findings in a logical form. However, a Greek physician by the name of Galen influenced many Renaissance physicians at the time, which made the possible success of his theory difficult, as patients deserted his practice and the medical community questioned his success. William Harvey shows a view of The Motion of the Heart and Blood in animals that reflects knowledge he had gained and the support of Kings Charles and James 1 through publicity and valued opinions. Harvey's intention was to inform the readers and fellow physicians that the blood flowed around the body, which is what he

Inhale. Exhale. Were the words coming out my father’s mouth as I finished a dreadful mile sprint. My heart pumped faster, as I felt blood rushing throughout my body. One beat at a time, my heart circulated blood through each chamber. It amazed me how a determined physician known as William Harvey discovered the process. After the discovery of the human heart, analyst grew curious to learn how a single muscular organ was able to pump blood thought the body. In the fourth century a Greek physician known as Aristotle described the beating heart as a three-chamber organ that was the center of the circulating blood .In the early 1400’s an Italian anatomist know as Leonardo Da Vinci believed the heart circulated through two chambers. Yet, it was not until the English physician known as William Harvey who confirmed with reason and

He did understand that blood travelled in veins and arteries and the difference in blood that each of the structures would carry. On the other hand, he does not describe how exactly blood circulation worked or how these impurities, which disrupted the homeostasis of the four humors, travelled around the body to cause disease. He certainly did not understand circulation at a cellular level, for, as mentioned before, cells and bacteria were discovered much later in the 17th century. Medieval Western European physicians had to rely on leech books and had no other choice but to purify blood of the sick by using leeches, not knowing other treatment methods that are more effective and less dangerous than

A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.

Andreas Vesalius, a Belgian physician, is known as the founder of human anatomy for revolutionizing medicine and biology through his findings of the anatomy of the human body. From 1533 to 1536, Vesalius studied at the University of Paris. There, he learned to dissect animals and obtained many human corpses to dissect too. He devoted most of his time to studying human bones, plentiful in cemeteries throughout Paris. At the time, Vesalius relied on the theories of Galen, a Greek physician, until he realized that the books on anatomy that were written by Galen were based on the dissections of animals, not humans. Vesalius’s book on anatomy, commonly known as the Fabrica, was printed in 1543. This book became widely known, detailing and teaching

“The heart then seems to pause until the next beat of the ventricle occurs in a regular fashion”

First, Galen’s book of anatomy is a helpful book of life, but Vesalius corrects his mistakes after mistakes. Although Vesalius needs to use Galen’s book as a material to teach students, Vesalius still encourage the students what they actually see. Second, Giovanni Borelli as a mathematician broke down a body into different component parts and he defines that life reduces to physical law. However, there is no a constant force which can drive a body.

In 1533 Vesalius transferred to the medical school of the University of Paris. One of his two teachers of anatomy there was Johann

William Harvey was a distinguished physician of the seventeenth century. Harvey was educated by some of the great scientists of his time and was highly knowledgeable of the scientist theories preceding his time. Harvey was greatly intrigued by the views of the ancient Aristotle and developed a number of his own ideas based on Aristotle’s theories. It was from Aristotle’s theory of the primacy of blood that allowed Harvey to make breakthroughs about circulation and generation of animals. His advancements greatly enhanced the study of anatomy. Harvey also revolutionized the means by which science was performed through the use of innovative, investigational techniques. William Harvey became a
