Erythrothyte size：Diameter7.5-8.5 um. shape：biconcave circular disc morphology：no nuclei other organelles, varieties. ABO Antigen: blood group. contents：haemoglobin(Hb)。 amount： 35-55lakh/mm3。 Reticulocyte premature RBC:left some ribosome in the cytoplasm. Amount:0.5%-1.5%. Can synthesize Hb.   leukocytes(white blood cell, WBC) EM Lymphocyte!!! * * blood Constituents of blood blood plasma （55%） blood cell （45%） Ery Leu Blood platelet water（90%） others (erythrocyte,red blood cell,RBC) staining method：Wright or Giemsa. SEM WBC granulocytes Agranular leukocytes neutrophils(60-70%) eosinophils(3%) basophils(1%) lymphocytes(20-30%) monocytes(5%) Depending on what? （LM） Neutrophilic granulocyte amount：60-70 %. Dia : 10-12um. nuclei：variable. roddish several lobes（2-5）. Granules: fine, stain lightly. functions：chemotaxis phagocytosis. （EM） Neutrophilic granulocyte Nuclear lobes Azurophilic granules specific granules (LM) Eosinophilic granulocyte amount：0.5-3%. Dia:10-15um. nuclei：two-lobes. granules：large, stain brightly with acid dyes. Functions:chemotaxis amoeban movement. *inhibit allergic reaction. *kill parasite.
