Leukocytes are classified into :
Granular & Non-granular leukocytes.
Granular leukocytes are :
Neutrophils 40-70% ,
Eosinophils 1-6% ,
Basophils 0-0.5% .
Non-granular leukocytes :
Lymphocytes 20-40% ,
Monocytes 3-8% .
Granules of Eosinophils are :
Acidophilic
Basophils & mast cells releases :
Histamine & Heparin
At EM, Macrophage have many :
Lysosomes
B-lymphocytes are activated & form :
Plasma cells
Basophils maybe absent in
Blood film
RBCs 4 characteristics :
Contain hemoglobin, Changes shape, Diameter= 7.2 um, Biconcave.
Neutrophils have
Lobulated nuclei, neutral granules, Phagocytic function, Diameter = 10 to 12
Lymphocytes nuclei :
Large rounded nuclei
Hemoglobin is
Cell inclusion & Endogenous pigment
Blood platelets =
150000 to 450000 cm3
2-5 um diameter
Monocytes enter connective tissue and are called :
Macrophage
Basophils have
Lobulated nucleus with basophilic cytoplasm, Diameter =10 to 12 um.
What protects body against blood loss
