hematology:-branch of physiology deals with study of body fluid connective tissue
blood:-
plasma:-
fluid connective tissue -
1)water, solid content(organic and inorganic)
2)formed elements:-erythrocytes ,leococytes ,platelets
plasmaprotein present in the plasma there are four types.
types:-
1)albumin:-major quantity,total quality of plasma protein
6-6 gm%(100 ml of blood)
-4-4.5.gm% and weight 6900 daltons -smallest molecule weight
-collidalosmotic protein
2)globulin:-half of albumin
-globular shaped protein
-IgG,IgA,IgC
quantity:-2.5-2.28 gms molecular weight
molecularweight:-4300000 daltons
3)fibrinogen:-0.3 gms-fibrin thread
molecular weight -340000 daltons
4)prothrombin:-0.1gmsd
-blood coagulation
immunoglobulin:-
it provides immunity and antigen
types:-
IgA -tear ,saliva,surfactant
2)IgD -synthesis from b lymphocytes-humeral immunity
3)Ige produced in allergy condition
4)igG-immunity to the foetus throuh placenta
5)igm -microbes invades to the infection
functions of plasma protein:-
1)fibrinogen and prothrombin -role:-helps in blood coagulation
ii)globulin-provides immunity against antigen by providing anti bodis
iii)albumin-collidal osmotic pressure of blood ,helps in maintaing
iv)protein-protein -protein reservoir during starving
buffering action;-plasma protein can regulate PH
plasma protein +WBC -triphone -to repair injured tissue
