A person with blood group O can donate blood to those having blood group A but cannot recieve blood from A to O . Why ? ( 2m)
Answers
Answer:
People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group. ... Their plasma does not contain A or B antibodies and can be transfused safely to all blood types.
Answer:
Explanation:To be more specific people with O negative can donate blood to any person and not receive from them.
It is because of the antigen present on the blood cell and antibody present in the blood. Blood group O contains antibody A and antibody B and it has no antigen.
When a person having blood group O receives blood from another person having blood group for example A then the receivers body which already contains antibody A will destroy the RBCs coming from the donor (a reaction between antibody and antigen takes place which results into destruction of RBCs.)
