Misconceptions About Vaccines

Decent Essays

Vaccines are largely debated within today’s world. There isn’t much debate within the medical community, but there is debate between the medical community and the general public. There are some people in the public who have certain misconceptions about vaccines, a couple being that vaccines cause autism or autoimmune disorders. However, these claims have been studied extensively, and there is no scientific evidence backing these claims. These misconceptions claim that the vaccines affect the lymphatic, circulatory, and the immune system. “The lymphatic system is the system of vessels, cells, and organs that carries excess fluids to the bloodstream and filters pathogens from the blood” (OpenStax, 2017). The main function of the lymphatic system …show more content…

The spleen “controls the amount of red blood cells and blood storage in the body, and helps to fight infection,” (Zimmermann, 2016). Tonsils are also lymphatic cells and organs, located in the throat. A large majority of the population have theirs removed, mostly due to medical reasons. The organs and lymph nodes are able to detect harmful bacteria and fight infection by releasing white blood cells, called lymphocytes. There are four main types of lymphocytes: B cells, T cells, plasma cells, and natural killer cells. B cells produce antibodies to fight bacteria; while t cells don’t secrete antibodies, but instead “perform a variety of functions in the adaptive immune response” (OpenStax, 2017). Plasma cells are similar to B cells, due to the fact that they also are able to produce antibodies. The natural killer cells contain cytotoxic granules as a defense …show more content…

The main function of the circulatory system is to keep blood pumping throughout the body, pumping, on average, 5 liters a minute. Along with pumping blood, the heart pumps waste, nutrients, and oxygen to other organs. Each artery and vein has a specific function, carrying blood to and from different parts of the body. The carotid arteries, both external and internal supply blood to the head. The celiac artery supplies the majority of blood to the trunk, and it is the only artery which allows the organs it supplies to receive an adequate blood supply. The subclavian arteries are the main arteries of the upper extremities, but eventually branch off into the axilla, where they fittingly become known as the axillary arteries. Finally, the second largest artery of the body, the femoral artery, is the main blood supplier to the lower limbs. The two main veins of the body are the inferior and superior vena cava. The superior vena cava returns blood to the right atrium from the upper half of the body. The inferior vena cava does the opposite, carrying blood from the lower half of the body also to the right atrium. The blood vessels of the circulatory system and the organs of the lymphatic system work in conjunction in order to maintain homeostasis. The lymphatic system is able to carry excess fluids to the blood stream, while also filtering pathogens from the blood. 20 liters of plasma
