Answer: b, c, d Eosinophils constitute 1% to 3% of the leukocyte population of the bloodstream. They also reside in tissues and they exhibit phagocytic capabilities. They are less effective as bactericidal cells than neutrophils, but play a major role in defense against parasites. Eosinophils are primary effectors in allergic reactions by virtue of IgE receptors (which are not found on neutrophils). Basophils are fully differentiated cells released into the circulation from bone marrow. Basophils are the major, if not sole, source of histamine in the blood. Histamine is a vasoactive amine and the major mediator of the IgE-mediated immediate hypersensitivity response. Histamine release from basophils is induced by complement products as well as by IgE receptors. Mast cells are formed from
