1. BLOOD
by:-
Pinky Varshney

2.  The cells of our body need nutrients, oxygen
and other essential substances for healthy
functioning of an organism
 In lower organisms such as sponges and
coelentrates the water facilitate the
exchange of the substances
 In higher organisms the Blood is the most
commonly used body fluid

3. Blood is a connective tissue
It comprises of
 Fluid matrix
 Plasma
 Formed elements

5.  Straw coloured, viscous,
 constitutes 55% of blood
 90-92% of plasma is water
 6-8% are proteins which
include
Fibrinogens , Globulins and
Albumins.

6.  Constitute 45% of blood
The Formed Elements Include:-
 Erythrocytes (R.B.C.),
 Leucocoytes (W.B.C.) and
 Platelets

7.  Are called Red blood cells.
 There are 5 to 5.5 millions
of RBC per mm3 of blood
 Formed in Red bone marrow
 Devoid of nucleus
 Are red due to presence
of Haemoglobin
 Life span of 120 days
 Are destroyed in spleen

8.  Are known as White Blood Cells.
 They are nucleated
 Are colorless
 Are 6000 to 8000 per mm3 of blood
 Are divided into Granulocytes and
Agranulocytes
 Neutrophiles, Easinophiles and
Basophiles are Granulocytes
 Monocytes and Lymphocytes are
Agranulocytes

9.  Neutrophiles are most abundant and
Basophiles are the least
 Neutrophiles and Monocytes are phagocytic
 Basophiles secrete Heparin, Serotonin and
Histamine
 Lymphocytes are of two types B and T forms

10.  Are called Thrombocytes
 Are produced from Megakryocytes
 There are 150000 to 350000 platelets per
mm3 of blood
 Function is coagulation and clotting of blood

11.  Various types of blood divided into two
 ABO
 Rh

12. Done on the basis of presence or absence of
antigens and antibodies on RBC surface.
Discovered by Karl Landsteiner

13.  AB blood group- Universal acceptor
 O negative blood group – Universal donor

14. A type of antigen similar to Rhesus monkeys
found on surface of RBC’s
