Blood Transfusions were a huge step into the field of medicine. Blood transfusions are when someone receives blood through an IV into their own blood vessels. People are able to be kept alive for longer if not for good with this discovery. Once they figured out how blood circulated throughout the body, blood transfusions became the next step. The first transfusion was done in the mid-1600’s using animals. It was only a couple years after that when a transfusion was performed on an actual human, and it worked. This discovery in medical science opened up a whole new world for people who were sick or dying. Not only did these blood transfusions help people who were losing blood, but it also helped cure people who were sick from diseases. Blood transfusions are an exceptional creation for the health of humans and this has made an enormous result in the way that physicians treat patients.
In the early 17th century, people were unsure about how the body system worked, especially when it came to blood. It wasn’t until the mid-1600’s that William Harvey discovered how the blood circulates throughout the body. Harvey was an English Physician whose discoveries greatly impacted medical science. This discovery completely changed the field of medicine. He first “observed the action of the heart in small animals and fishes” (Weisstein). When observing these small animals he concluded on how the blood circulates the bodies. He made many discoveries in which he announced the way the body works and how it uses blood. “He developed the first complete theory of the circulation of blood, believing that it was pushed throughout the body by the heart’s contractions” (Weisstein). There were still many gaps in the process of how the blood circulates, but this gave an overall look on the blood systems function. Harvey was the first to figure out the discovery that took off in the direction of blood transfusions. His discovery has saved many of lives to this day.
The first blood transfusion was attempted by Physician Richard Lower in 1665. Lower was also known as an English Physician but he made a huge impact for medical science. He performed this blood transfusion using dogs. He did this by “transfusing blood from an artery of one animal into a vein of a second” (Brown). This was the first step to the discovery of how blood transfusions could save people’s lives. Although they did not know this at the time, it soon took off into many wonderful creations for the medical field. Not only did Lower transfuse blood from one animal to another, he also tried to transfuse blood from one animal to a human. “Lower transfused blood from a lamb into the bloodstream of a clergyman named Arthur Coga” (PMID). This transfusion did not work because they were still unaware of the difference in blood types between an...
