Composition
Cells suspended in plasma
Procentage of plasma
60%
normal pH of blood
7.4
Haemopoiesis
Develop of red blood cell from other stem cells (liver, bone marrow lymph nodes, spleen)
erythrocytes
Red blood cells, non-nucleated, biconcave, haemoglobin-protein
leucocytes
White blood cells
Thrombocytes
Platelets
small, irregular, non-nucleated, formed in bone marrow, involved in clotting
Erythropoiesis
1 week, erythropoietin secreted by kidney
erythoblast
red blood cells-forming cells (normoblast)
Reticulocytes
Immature erythrocyte (anemia)
Classification leukocytes
granulocytes and agranulocytes
Granulocytes
70%, Granular cytoplasm, multilobed nucleus, myleoid tissue
classification granulocytes
neutrophils, eosinophils, basophils
neutrophils
90%, phagocytes in respond to infection
Eosinophils
against infection and allergic reactions, can leave blood also in inflamatory reaction
basophil
involved in inflamatory reaction, produce histamine and heparin
Agranulocytes
clear cytoplasm with big rounded nucleus
monocytes
large and horse shoe nucleus, phagocytosis, important role in immunity
lymphocytes
rounded nucleus classidied as B and T, 80%
Thrombocytes
