A person with blood group A has antibodies against blood group B. Therefore, if they were to receive blood from someone with blood group B, their immune system would recognize the foreign blood cells as invaders and attack them, leading to a potentially dangerous immune response.
On the other hand, blood group O is considered the universal donor because it does not contain A or B antigens on the red blood cells. This means that a person with blood group A can safely receive blood from someone with blood group O without triggering an immune response.
Similarly, a person with blood group A can receive blood from someone with blood group AB because blood group AB does not contain antibodies against blood group A. This makes blood group AB the universal recipient, as they can safely receive blood from any blood group without triggering an immune response.
On the other hand, blood group O is considered the universal donor because it does not contain A or B antigens on the red blood cells. This means that a person with blood group A can safely receive blood from someone with blood group O without triggering an immune response.
Similarly, a person with blood group A can receive blood from someone with blood group AB because blood group AB does not contain antibodies against blood group A. This makes blood group AB the universal recipient, as they can safely receive blood from any blood group without triggering an immune response.

Reason for Compatibility:
Blood transfusions involve mixing blood from a donor (the person giving blood) and a recipient (the person receiving blood). Red blood cells have antigens (proteins) on their surface that determine blood group. The recipient's immune system must not recognize these antigens as "foreign" or it will attack and destroy the donor's red blood cells.
Blood Group A Compatibility:
- Individuals with blood group A have A antigens on their red blood cells.
- They have anti-B antibodies in their plasma, which recognize and attack B antigens.
- Blood from group A (A antigens) and group O (no antigens) does not contain B antigens, so it is compatible with the recipient's plasma (no anti-A antibodies).
Exclusion of Blood Group B and AB:
- Blood group B contains B antigens, which can bind to anti-B antibodies in the recipient's plasma.
- Blood group AB contains both A and B antigens, which can bind to both anti-A and anti-B antibodies in the recipient's plasma.
- Both B and AB blood would cause an immune reaction, leading to the destruction of donor red blood cells.
