3 functions of immune systemidentify infection eradicate/neutralize pathogen provide protective immunity for future Name of community of microbes that live mainly on skin and gutMicrobiota how do commensal bacteria help against pathogenic colonizationtake up space so that pathogens cannot grow there 4 categories of pathogensbacteria viruses fungi parasites (protozoa and worms)

Which one of the following is a characteristic of adaptive immune response and NOT a characteristic of innate immune response? Organ specific response Macrophages are the main cells Antigen-specific response Ancient system Rapid responseAntigen-specific response Which of the following is NOT one of the four main task of immune system?

NeutrophilsPhagocyte, makes pus MacrophagesPhagocyte, antigen presenting cell, scavenger dendritic cellphagocyte, antigen presenting cell, initiation or adaptive response, immune surveillance, immune tolerance Mast cellsAnti allergy, anti tumor, immune bomb, degranulation, IgE-FceR Eosinophilsanti allergy, anti tumor, IdE-FceR Basophilsanti allergy, anti tumor, IdE-FceR NK cellsnatural killer cells, cytotoxic killing, anti viral, anti tumor

how do NK cells recognize and kill infected cells?-altered/absent MHC1 presentation -use cytotoxic granules (granzyme, perforin) which cells contribute to the anti-parasitic immune response-eosinophil -basophil degradation of pathogens occur only in the lysosomestrue toll-like receptors are always membrane boundtrue Naive T cells find and enter the secondary lymphoid tissues throughfollowing chemokine gradient as well as binding adhesion molecule at HEV TH17RORgammaT
