includes cilia, mucous membranes and dendritic cells-Innate immunity immunobiological response bought by production of antibodies-Humaral immunity immunological response that kills infected host cells-cellular immunity use(s) BCRs to recognize etitope. First step in clonal selection-immature B cells Phagocytes that engulf anything foreign. Eventually display etitope to helper T cells using MHC I or II-dendritic cells lymphocytes that activate B cells and CTLs-Th cells produce and secrete antibodies-plasma cells Kill(s) infected host cells-cytotoxic T cells Solution includes cilia, mucous membranes and dendritic cells-Innate immunity immunobiological response bought by production of antibodies-Humaral immunity immunological response that kills infected host cells-cellular immunity use(s) BCRs to recognize etitope.
