E/M: • Few mitochondria and • endoplasmic reticulum. • Two types of granules are present:- • Specific granules: • Numerous & small in size. • Contain bacteriostatic and bactericidal substances. • Azurophilic granules: • Few in number & large in size. • Contain hydrolytic enzymes (lysosomes). • Life span: 1- 4 days. Dr. Amal M. Moustafa, , Department of Histology & Cytology
Function:- • Defense against microorganisms. • When microorganism invades the surrounding tissue, the neutrophils migrate from the capillaries and phagocytose it (so called microphages). • They also secrete proteolytic enzymes. • During infections, they stimulate the bone marrow to produce more leucocytes (neutrophilia). • They attract monocytes to the infected area. • Precipitate in pus formation. • They secrete trephone substances, that help in healing of wounds.
