Document Summary
Immunity: relative to the immune system, describe the function(s) and clinical consequence of abnormality for: t lymphocytes, neutrophils, complement, spleen, b lymphocytes,eosinophils, platelets, basophils/mast cells, lymphatics,thymus, Identify clinical examples of each: describe the significance of and appropriate clinical response to: total wbc value. A "shift to the left" = elevation of immature neutrophils (also called "stab" or "band" cells), the tissue is red, warm, swollen and painful. Stem cells can form: lymphocytes (t, b and large granular lymphocytes). 30% of wbc are lymphocytes: cytotoxic t cells fight off viruses and cancer, helper t cells coordinate the immune response, b cells make antibodies, polymorphonuclear cells (neutrophils, basophils and eosinophils, mast cells, megakarocytes that produce platelets. Each b lymphocyte makes only one shape of antibody. Plasma cell is a type of b-cell that secretes antibodies. Memory cells are long-lived, inactive cells that are activated at subsequent exposure to an antigen.
