  • lacking globulins

     

  • lacking albumins

     

  • lacking clotting factors

     

  • lacking antibodies

     

(3)

Serum is the fluid that separates from blood plasma on centrifugation. Serum is essentially similar in composition to plasma but lacks fibrinogen and other substances that are used in the coagulation process.

 



Q 12 :    

Erythropoiesis starts in                 [2015]

  • spleen

     

  • red bone marrow

     

  • kidney

Q 13 :    

Person with blood group AB is considered as universal recipient because he has            [2014]

  • both A and B antigens on RBC but no antibodies in the plasma

     

  • both A and B antibodies in the plasma

     

  • no antigen on RBC and no antibody in the plasma

     

  • both A and B antigens in the plasma but no antibodies

     

(1)

Individuals with AB blood group have both antigen A and B on their RBCs, and no antibodies for either of the antigen in their plasma. Type O individuals are without A and B antigens on their RBCs, but have antibodies for both these antigens in their plasma. Individuals with blood group AB can receive blood of A, B or O group, while those with blood group O can donate blood to anyone.
