We have the process of oxidization which basically is the process by which we stimulate the process of phagocytosis. We call upon these phagocytic cells such as macrophages and neutrophils. And we also have the process of aggloutnation taking place. And what agglutination means is it's when many of these antibody antigen complexes get together and they basically inhibit that pathogenic agent from acting and infecting our cells. And so eventually that conglomerate of antibody antigen complexes is engulfed by our phagocytic cells. And finally we also have the promotion of formation of antibodies.
