Document Summary

Understand why immune system does what it does. Work through process-what is the goal and how does it achieve the process. Each person produces about 10 million types of b-cells (multiple of each type) Done to prepare for all pathogens to be encountered. Body cant predict which pathogen will be encountered. Once a few b cells are activated. Done to produce huge population of one type of b cell. When cell turns one type to another. Lives for few weeks and floods antigens. If it encounters the same pathogen immediately turns into plasma cell. Key: doesn"t need t helper cell; automatically activated within a 1-2 days instead of 7-10 days. Infected with antigen w/ no receptors to fight itnatural selection. Two binding sites for crosslinking creating insoluble clumps (agglutination) Making it easier for phagocytic cells to kill. Know how to read it apply lecture learning. Can measure how much antigen was in the blood.
