The coughing, sneezing, vomiting, and the restless nights is a place where we have all been quite a few times; and sometimes it feels like it could be for the last time. What people don’t think about is why all this is happening to them. Little do we know our cells are undergoing just as much trouble as we are; a lot more goes on in the microscopic world than people think. Elie Mitchnikoff could tell you all about this. He was a biologist who was best known for the pioneering in the research of the immune system. In 1882 Elie mitchnikoff won the Noble Prize in Medicine for his work on phagocytosis when experimenting on larvae in starfish. Phagocytes are …show more content…
Adaptive immunity or specific immunity is the bodys way of defending itself by specific invading antigens like bacteria, toxins viruses, and foreign tissues. This is all based on having exposure to things. When you have resistance to a certain virus, bacteria, or etc this is your adaptive immunity working. It is overall an inflammatory response.
Fore mostly, the immune systems first line of responsibility is to keep anything in the body that can cause disease out of it. Viruses, fungi, protein, bacteria and parasites that cause this are called pathogens. If these do get into the body it’s the second line of defenses responsibility to eat and destroy them to keep us from dying. This is where phagocytes come into play. Phagocytes have receptors to anything that is not good for the body. Phagocytes only belong to the innate immune system. Which are a class of cells that eat up pathogens.
There are two major types of phagoctyes. There are neutrophils and macrophages. Once an infection happens nuetrophils and monocytes go to that area. This process is
