Document Summary
*if the amount of pathogens or virulence goes up, this side of the teeter totter goes down and the happy face in the middle is sad. **if the amount of immunity goes up, that side of the teeter totter goes down, and the happy face in the middle is sad. Autoimmune disease: where the immune system recognizes some cells as the enemy. Acute inflammation-sepsis: o157 is doing exactly this type of activity. Acute inflammation is a result of bacteria cells entering the blood stream. People are killed by the immune system that reacts to this. Chronic inflammation-cancer: hepatitis a, b, and virus are causing problems because they are making the body act in chronic ways against the infection. Cells are killed by the virus sand then cells are born back because liver for example knows how to regenerate it itself. At a certain point, there is going to be a mutation in this process, and the result can be cancer.
