Document Summary
White blood cells: leukocyte (lueko: white cyte: cell) always have a nucleus. Leukemia: (cid:1005)(cid:1004)(cid:1004)(cid:1004)rbcs=(cid:1005)wbcs is(cid:374)"t true here, too (cid:373)a(cid:374)y wbcs produced: leuko->white emia->blood (white blood) Phagocytes function: defend against invading microorganisms by ingesting and destroying them, inflammatory. Attraction of phagocytes(chemotaxis) to microorganisms, antibody complexes, and other mediators of inflammation: 2. Fuse cell lysosomes with ingested microorganisms: 5. Monocytes: form a link to the specific immune system by processing antigen for presentation to lymphocytes and producing interleukin-1, initiating fever and lymphocyte activation. Eosinophils: provide a defense against metazoan parasites and modulating the inflammatory process; respond to histamine etc. Basophils: not true phagocytes, but contain large amounts of histamine and other mediators of inflammation: eos & bas: may seen responding to systemic allergic reactions and invasion of tissues by parasites. Lymphocytes: responsible for both humoral and cellular immunity. Spleen: b=red pulp t=periarteriolar lymphoid sheaths: their function has both afferent and efferent components.
