Document Summary

Like general vacuum cleaner, helpful for eliminating larger things. Set of circulating proteins found in blood. Recognize sugars on cell wall of bacteria, come together in configuration that punctures cell wall and allows inside to leak out to kill bacteria. T helper 2 (th2) cells tell b cells to make antibodies. T helper 1 (th1) cells control cell mediated immunity. Humor is part of blood where antibodies are (top layer from centrifuge) Bacteria something that is unique (preferable when on surface, but can be interior as well) Clumping of bacteria is useful b/c immune system will recognize it. If antibody cannot distinguish self from non-self autoimmune issue. ** do not want to boost immune system too taxing, overstimulation can cause allergies. Antibody detection infection is starting, pathogen cannot be detected by taking clinical sample. By determining which antibodies are present, can determine how long infection has been present, etc. Take in the entity and prepares antigen for presentation.
