6 Fun facts about the circulatory system:
If you stretch out all the arteries, veins, and capillaries; they will stretch out to 100,000 KM in distance, and this distance circles the Earth 2.5 times. The capillaries make up about 80% of the length, even though they are the smallest of all blood vessels. blood cells are roughly the same length and width as capillaries. Capillaries are 8 micros or 1/3000 inches big. However, some capillaries are smaller than blood cells, which forces these blood cells to change and distort shapes in order to go through these capillaries.
The heart can still beat, even though if it is separated from the body. The heart can still beat outside from your body because it generates its own electrical impulses. If the …show more content…

The earliest evidence dates back to 1600 B.C in an ancient Egyptian medical document. The document states that there is a connection between the arteries and the heart in a physiological way. The document also states that if a person breathes air it comes to the lungs, and then the air enters the heart and rushes into the arteries. The Egyptians believed that the heart gives you feelings of emotions, wisdom and memory rather than the brain. Egyptians when they mummify their kings, they actually remove the heart and store it in a jar, but the brain is discarded rather then being put in the jar.
Physicians have been following the circulatory model incorrectly for over 1500 years. In the year 200 A.D, a Greek physical and philosopher named Galen of perigean had an idea for what the circulatory system looks like, so he proposed a model. He said that circulatory system has 2 types of blood; venous and arterial these types of blood have different roles and functions. He said that the circulatory system has 2 pipelines of one way systems of blood distribution. He also stated that the liver makes venous blood that the body actually uses. He said that the heart sucks the blood rather than pumping

achievements have been recognized. Charles Richard Drew made a discovery that blood could be preserved and if the liquid red cells were separated from the plasma, then they both can be preserved separately. In this process, the blood can be reconstructed when needed. With this process, blood can be stored undefined while being in a separate state. This discovery made blood transfusions more effectively and with a reasonable price.

Galen who was an ancient Greek physician who believed that food from the alimentary canal was converted into blood in and by the portal veins. “If a man take no other food for a prolonged period he will have blood in closed in his veins.” (Document 5) Later, Robert Boyle noticed that Valves in the Veins gave free passage to the Blood towards the heart, but opposed passage to the venal blood the contrary way. Robert Boyle’s discovery proved that Galen’s theory was incorrect which proves science is not always right.

Harvey William Harvey’s seminal work “On the Motion on the Heart and Blood in Animals” initiated modern medicine. Harvey’s arguments were detailed readily verifiable and though they did endure a fair bit of criticism when released, in most areas, they were accepted within his lifetime. Once his simple notion of the circulation of blood was carefully described others were able to see and understand its validity themselves. I will argue that William Harvey’s theory which used inductive reasoning to show, with experiments, how blood flowed from veins to arteries through the heart and deduced the existence of capillaries to return blood from arteries to veins. One of the main understandings of the day, proposed by Galen of Pergamon nearly 1500 years earlier, was that blood was a resource that was produced in the liver and consumed in the tissues and the brain.

In 1539 Vesalius wrote an essay on bloodletting, where he described the veins that draw blood from the side of the torso, which later led to the discovery of the circulation of the blood by an english physician named William Harvey. His essay was a spectacular piece of work as everything Vesalius did, medical historians always appreciate Vesalius work but his groundbreaking book “ De Humani Corporis Fabrica” published in 1543 took them all. “ De Humani Corporis Fabrica” was published the same year Vesalius was offered the post of imperial physician at the court of Charles V, which is why I figure the book was dedicated to the emperor Charles V. Vesalius also opened his own private practice, but later on in 1556 Charles V abdicated his throne. Vesalius was immediately re-employed by his successor Philip II. Vesalius set out on a pilgrimage to Jerusalem, when he reached there Vesalius received a letter from Padua inviting him to accept the chair of anatomy and surgery.

William Harvey took Vesalius's work and expanded upon it. He developed the concept of full circulation throughout the body not only between the heart and lungs. He theorized that the heart was an organic pump, and it could not be quantified through mathematical equations(Gregory). Also inspired by Vesalius’s work was Charles Darwin. A better understanding of the human body allowed him to understand the concept evolution by studying the differences between humans and animals(Comparative Anatomy: Andreas

It was part of the idea that blood was just a “humor” that had to be in harmony with the other “humors” of your body: blood, phlegm, yellow bile, and black bile. If you had too much blood in your body that meant that your humors were out of harmony so blood had to be drained.

According to Rosemary, the Victorian gentleman believed that ‘what one can see and prove constitutes reality’ (275). Stoker’s Dr. John Seward embodies this sort of scientific rationality. When he finds out about Lucy Westenra’s illness and somnambulism, he attempts to heal her with blood transfusions: ‘Lucy had got a terrible shock, and it told on her more than before, for though plenty of blood went into her veins, her body did not respond to the treatment as well as on the other occasions’ (Stoker 160). Lecercle points out that blood transfusions can be seen as the inverse of vampirism (71). They are essentially modern medicine’s attempt to bring the supernatural under control.

During these years, I have read and reviewed hundreds of general biology textbooks. The topic of blood groups and transfusion is discussed in these books, but with no reference to Charles Drew. General biology textbooks refer to Charles Darwin as the father of evolution, Carolus Linnaeus as the father of taxonomy, and Gregor Mendel as the father of genetics. They should refer to Charles Drew as the father of the blood bank. I learned about Dr. Drew and his achievements from the Internet.

The heart muscle is in an inflammatory condition and contains a large number of white blood cells. This indicates that the heart was alive at the time the sample was taken… They require a living organism to sustain them… What is more, these white blood cells had penetrated the tissue, which further indicates that the heart had been under severe stress, as if the owner had been beaten severely about the chest.” The blood type of the material was AB.

Blood transfusions is a significant advanced-technology in the novel; meanwhile, the Count Dracula’s blood represents an unexplainable miracle for healing people’s illness, but not save them. The role of technology, especially for the blood transfusions carried out by Professor Van Helsing, which reflects the rapid and advanced technological changes and takes place in the Victorian society. For instance, Dr. Seward, Van Helsing, and Morris all give Lucy blood transfusions for saving her life, as Van Helsing said: “A brave man's blood is the best thing on this earth when a woman is in trouble. You're a man, and no mistake” (139). That not only indicate the newest scientific thought about blood transfusion after they noticed that Lucy’ anemias that could be saved if they transfuse blood to her; also, it indicates the masculinity symbol for a man doing the blood transfusion for a

The human body is made up of complicated physiological processes, one of them being the process of transporting blood around the body by a system known as the circulatory system. This system carries blood around the body from the heart to the organs, tissues and cells of the body. Blood is made up of blood cells, namely erythrocytes, thrombocytes and leucocytes – in an extracellular matrix called plasma, which makes up approximately 55% of the blood. It is essential that blood is transported to the organs and systems of the body in order for these systems to function. The fluid is transported through blood vessels known as arteries, veins and capillaries in a succession starting and ending at the heart.
