Question

Explain with reasons - Person with 'O' blood group is considered as 'universal donor'.

Answer 1

Dear Student,

◆ ABO blood group system -

• Carl Landsteiner classified blood groups according to presence/absence of antigens A & B on RBCs.

1. Group A have A antigen.
2. Group B have B antigen.
3. Group AB have both A & B antigen.
4. Group O have no antigens.

# Group O is called universal donor because -

• Group O doesn't have any antigens on its RBCs.
• So our immune system system doesn't react to RBCs of O blood group as there is no antigen.
• As this blood can be given to person with any blood group, person with O blood group are universal donor.

Thank dear...
