most abundant circulating wbc. 4k per microliter. usually first to arrive at infection, emigration, (+) chemotaxis, limited phagocytic, fill up with pathogen.
defensive compounds. defensis and oxidant toxins
poke holes in membrane of pathogen, ruptures
damage and kill pathogen
emmigration, (+) chemotaxis, small amount phagocytic. 165 per microliter
histamines and digestive enzymes
release these enzymes on parasite, digest it
44 per microliter. emmigration, most basophils are in tissue, (+) chemotaxis, almost no phagocytosis.
heparin and histamines
2k per microliter. emmigration, can move back and forth between blood and tissues. (=) chemotaxis, no phagocytosis. specific immunity. provides memory or immunity to pathogen after initial exposure.
t cells and b cells
450 per microliter. emigration, move into tissue and converts in macrophages, (=) chemotaxis, phagocytic (agressive and unlimited). some of these in specific tissues such as lung, skin, gi tract, bone marrow, spleen, lymph nodes and liver
