Document Summary

Diapedesis: can leave bloodstream and have a chemical trail that lead it to bacteria . etc, called chemotaxis. Leukocytosis: body"s response to bacterial or viral invasion, # of wbcs can double within hours. 5 types of wbcs: never let monkeys eat bananas know all: neutrophils. Spherical, larger than rbcs, lobed nuclei, cytoplasmic granules: neutrophils: at least 50%. Two types of granules that take up acidic and basic dyes: hydrolytic enzymes (divestive) and antibiotic like proteins called defensins. Called polymorphic leukocytes because they have odd shapes. Phagocytic cells: ingest and destroy bacteria, thus increased in the case of infection: eosinophils: less common. Important against parasites, too small to kill individually but many of them can kill them. Numbers elevated in the case of allergy, carry immune complexes out of the body: basophil: 0. 5%; contain histamine-vasodilator and can cause leaky capillaries which can result in wbcs leaving circulation to go to site of infection.
