Neutrophils 60N70%o of the leukocyte count Spherical, with a nucleus consisting of two to five lobes Neutrophil cytoplasm is lightly eosinophilic and contains two types of granules Specific granules: contain bactericidal enzymes. Azurophilic granules: are primary lysosomes containing peroxidase and hydrolytic enzymes The active phagocytes of bacteria and other foreign agentsNeutrophils ◼ 60~70% of the leukocyte count ◼ Spherical, with a nucleus consisting of two to five lobes. ◼ Neutrophil cytoplasm is lightly eosinophilic and contains two types of granules. ◼ Specific granules: contain bactericidal enzymes. ◼ Azurophilic granules: are primary lysosomes containing peroxidase and hydrolytic enzymes. ◼ The active phagocytes of bacteria and other foreign agents
