1. BLOOD(RBCs)

2. 1. Definition.
2. Lineage blood.
3. Component of blood.
4. Histology & physiology of RBCs.
5. ABO groups.

3. Is a fluid connective tissue which transports from
one part to another.
5-6 liters(L)

5. •RED BLOOD CELLS (Erythrocytes)
• WHITE BLOOD CELLS (Leukocytes)
• PLATELETS (Thrombocytes)
55% PLASMA45% cells
91 % H2O 9 % Solids

7. WHITE BLOOD CELLS (Leukocytes):
They are part of the immune system and destroy infectious agents
called pathogens.
PLATELETS (Thrombocytes):
The main function is clotting

8. The most abundant cells in our blood; they are produced in
the bone marrow and contain a protein called
hemoglobin that carries oxygen to our cells.

9. Survive in circulation for an average 120 D.
Normal RBCs count:
In men 5.4 million/µl.
In women 4.8 million/µl.
Each human RBCs is about 7.5 µm in diameter ,
2 µm think in rim ,and 0.8 µm in center,
biconcave shape

10. 1. Sex.
2. Severe exercise.
3. After meals.
4. Hypoxia (which stimulates production of
erythropoitin).

11. 1. pregnancy.
2. Old age.
3. Sex.

12.  Transport of:
 Gases, nutrients, waste products
 Regulation of pH and osmosis
 Maintenance of body temperature
 Protection against foreign substances
 Clot formation
19-12

13.  The main function of RBCs is transport of O2 or
CO2 , between the tissues and the heart.
 They are nonnuclear cells containing only
Hemoglobin (Hb).

14.  According to the ABO Blood typing system
there are four different kinds of blood types:
 A,B,AB ,O
