1. Blood and Circulatory system
Composition
Function

2. Blood-Composition

3. Blood-composition

4. Plasma Straw coloured fluid 55% of blood volume
Cells suspended in plasma
Helps transport of food, Carbon dioxide,waste and salts.
92% -plasma is water
8%-organic and inorganic substance

5. RBCs-Red Blood Cells Most abundant cells 99% of blood volume
Contains red colour pigment called haemoglobin
Haemoglobin carries oxygen
Produced in bone marrow, ribs etc
4-6 million RBCs per cubic millilitre
No nucleus
Life span-120 days

6. WBCs-White blood cells
Colourless-leucocytes
1% of blood volume
Largest cells of blood
Fight against infections
Protects from Germs, bacteria

7. Associate with allergic reactions
Types of leucocytes
Leucocytes
Granulocytes
Neutrophils
60-65%
Phagocytic
Eosinophils
Associate with allergic reactions
Basophils
0.5-1% Secrete histamine serotonins, heparin involved in inflammatory response
Agranulocytes
Lymphocytes
20-25% immune responses
B lymphocytes
T lymphocytes
Monocytes

8. Platelets Small irregular bodies Thrombocyte 10 days No nucleus
Chemicals-clotting
Prevents bleeding
Produced in bone marrow
1.5-3 lakh platelets in each millilitre of blood

9. Regulates body temperature
Functions of blood
Transportation
Fights diseases
Regulates body temperature

10. Blood Groups/Blood types

11. Human ABO blood groups and their compatibility

12. Rh-system
1-The Rh system consists of Rh-positive (Rh) and Rh-negative (Rh) groups.
2-These groups are identified on the basis of the presence of an antigen called Rh factor.
3- If in a person Rh factor is present, he is Rh-positive and if not, he is Rh-negative.
4-These two blood groups are also incompatible i.e. in blood transfusion an Rh-negative person should not be given Rh-positive.

13. Blood circulation

14. Components of Circulatory system
Lymph
Blood
Blood vessels
Arteries
Veins
Capillaries
Heart

15. Lymphatic system
Lymph-clear yellowish, slightly alkaline, coagulable fluid, WBC
Middleman between blood and tissues.
Carries plasma proteins synthesized in liver to the blood.
