NK cells.b. stomach PH.c. phagocytes.d. all of the above. The second line of defense against pathogens includes a. NK cells.b. Macrophagesc. Dendritic cellsd. all of the above.Write TRUE is the statement is True, otherwise write FALSE and explain why the statement is False. The complement system involves a set of genes that distinguish foreign cells from body cells. The alternative complement activation pathway involves the cleavage of C5 to form C9. The type of interferon present late in an infection is gamma interferon. Interferons cause muscle aches, chills, and fever. Toll-like receptors act to cause phagocytic chemotaxis. Lymphocytes are large agranulocytes. Opsonization occurs when a phagocyte’s pseudopods surround a microbe and fuse to form a sac. Defensins are antimicrobial peptides of the first line of defense.
