(Eosinophils/Basophils/Neutrophils) are the acute inflammatory response cells of the body. They are markedly increased in bacterial infections and carry out immune functions via phagocytosis. They possess a multilobed nucleus and contain numerous, small granules filled with ALP, collagenase, lysozyme, and lactoferrin. They also possess larger, less numerous azurophilic granules (lysosomes) that contain proteinases, acid phosphatase, myeloperoxidase, and β-glucuronidase. They typically survive for hours to days*.
