Germ theory of disease

The Ohio State University Wexner Medical Center, “the leukocytes circulate through the body between the organs and nodes via lymphatic vessels and blood vessels. In this way, the immune system works in a coordinated manner to monitor the body for germs or substances that might cause problems.” Leukocytes comprises of phagocytes and lymphocytes, with each having a distinct function. Phagocytes cells consume foreign invaders, while lymphocytes cells create a memory system to recognize and…

Genetic mutations are believed to be a contributing factor to variation, diversity, and even evolution. This information confirmed a lingering suspicion that I had about genetic diseases. I previously knew that people were infertile due to conditions during embryotic development and this confirmed that suspicion by verifying that reproductive chromosomes are not distributed evenly and this causes infertility in people. I would like…

Increasing Immunization Rates From Ages Birth to 19 Why should we immunize our children? I believe children should be immunized to in order to stop an outbreak of a preventable disease in a community. By doing so, I believe one could save a child 's life from these diseases that such as Measles, Mumps, Rubella(MMR), Pertussis and Diphtheria with just a simple vaccination. It is recommended that children be immunized from birth to the age of 19. After the age of 19 they, should continue to…

humans are the driving force and others believe the environment is in control of human actions. Jared Diamond in Guns, Germs, and Steel believes that the environment determines the course of human history. William Cronon, author of Changes in the Land: Indians, Colonists, and the Ecology of New England, believes that humans have shaped the environment over time. In Guns, Germs, and Steel, Jared Diamond looks at the inequality experienced in the world from the perspective that the location of a…

The only thing worse than having an unknown disease claim the lives of so many is not knowing the cause or cure to stop it. The discovery of pellagra is credited to a Spanish physician, Don Gaspar Casal in 1763 after his records showed a disease caused from unbalanced diets due to economical status and high intakes of maize based foods. The newly discovered disease remained within Southern Europe and the Mediterranean for almost 200 years before making its appearance in the United States during…

addition, he was the first to actually prove the theory that the earth is round rather than a flat surface. Moreover, he was also the first person to cross the Atlantic in a time where people had limited knowledge about the waters. Despite Christopher…

In Guns, Germs, and Steel, Jered Diamond attempts to revolutionize the way we think about Europe’s rise to superiority. He tries to do this by proposing that Europe’s rise was the direct result of geography. Diamond believes geography gave the Europeans access to the best crops, and granted Europeans access to thirteen of the fourteen large, domesticized mammals. According to Diamond, these two fortunate circumstances allowed Europeans to develop societies that gave people the option to have a…

William Harvey came up with the theory of blood circulation. “Vehemently opposed at first, this discovery led to the realization that medications could be injected into the circulatory system, and blood could be transfused.” (Mitchell & Haroun) 2012. This is used still used today. Anton Van Leeunwenhoek also invented the microscope which was used to look at everything on a microscopic level. “Germs were only viewed under the microscope; the connection with disease came several centuries…

as opposed to the “folkloric” vampires found in the sources. He argues that the vampire of folklore are simply describing the natural decomposition process, but came to embody the fears the people of Eastern Europe had about death, calamity and disease. He shares the same status as Calmet, Summers, and Perkowski in that his work is sourced in almost all scholarship after him. There are a few works dedicated to explaining why vampires became such a matter of discussion in the academic circles…

Today, Louis Pasteur’s name has become almost synonymous with germ theory, vaccination, and immunology. His accomplishments include not just disease management, but include also the saving of certain business and national economies. For example, one of Pasteur’s first successes was in identifying the nature of fermentation, and showing the importance of yeast as a catalyst. Because of his work, distilleries in Lille, France were able to produce wine more regularly once Pasteur had discovered the…
