1. PHYSIOLOGY OF LEUKOCYTES. BLOOD TYPES

2. Function of leukocytes
1. Protective
2. Transport
3. Metabolic
4. Regenerator

3. Quantity of leukocytes and their changes
White cells are nucleated and somewhat variable in size and shape. Their numbering is 4-9•Giga per liter. The number of lymphocytes are – %,
monocytes – 3-11 %,
eosinophils –0,5-5 %,
basophils – 0-1 %,
juvenile neutrophile – 0-1 %,
relating to stab (rod-shaped) neutrophil – 1-6 %,
segmented neutrophil – %.
The number of leukocytes may increase or decrease.

4. Development of monocytes
common progenitor cell –
uncommited stem cell –
commited stem cell –
monoblast –
promonocyte –
monocyte –
tissue macrophage.

7. Development of lymphocytes
common progenitor cell –
bone marrow lymphocytes precursor –
lymphoblast –
prolymphocyte –
large lymphocyte –
small lymphocyte.
Lymphocytes in the fetus are thought to arise first in the thymus. Later they are found in lymph nodes, spleen, and other lymphoid tissues as well as in bone marrow.

8. Development of gtanulocytes
common progenitor cell –
uncommited stem cell –
commited stem cell –
myeloblast (basophil, neutrophil, eosinophil) – promyelocyte –
myelocyte –
metamyelocyte –
juvenile –
rod-shaped neutrophil (basophil, eosinophil),
segmented neutrophil, basophil, eosinophil.

10. Physiological role of T-lymphocytes
1. Immune memory.
2. Anti viruses immunity.
3. Anti tissue immunity.
4. Regulate phagocytosis.
Function of В-lymphocytes
2. Specific immunity. B-lymphocytes syntheses the immunoglobulins such as IgM, IgN, IgA, IgG, IgB, IgE.

12. System of mononucleares phagocytes
These is the system, which common the cells with one nucleus,
common origin from red bone marrow, common function of high specific phagocytosis

16. The index of nuclear’s changing of neutrophyls, it interpretation
NCN=(M+J+S1)/S2, where
M – myelocytes,
J– juvenile,
S1 – stab neutrophils,
S2 – segmented neutrophils
Norm is 0,06-0,09
