1) non specific - macrophage engulf pathogens and breaks them down 2) dendritic cells have the antigen fragments and present them to specific T helper lympho which activates it 3) cytokines released 4) cytokines activate specific B cell to produce antibodies which divides and forms clones 5) clones become short lived plasma cells that produce a large quantity of an antibody 6) small group of clones become long living memory cells for immunity
