Study Notes
Red Blood Cell Antigens
- Red blood cells, also known as erythrocytes, contain proteins on their plasma membrane that are genetically determined.
- These proteins are called red blood cell antigens, and they trigger the immune system to produce antibodies against foreign antigens.
- Agglutination is the clumping together of red blood cells, which can occur due to the reaction of antibodies to foreign red blood cell antigens during a blood transfusion.
ABO Blood Group System
- This system classifies blood based on the presence or absence of A and B antigens on red blood cells.
- Individuals inherit these antigens from their parents, determining their blood type:
- Type A: Inherits only A antigen.
- Type B: Inherits only B antigen.
- Type AB: Inherits both A and B antigens.
- Type O: Inherits neither A nor B antigens.
- Your body produces antibodies against the antigens not present on your red blood cells. For instance, individuals with Type A blood will produce anti-B antibodies.
- This is important for preventing the immune system from attacking its own blood cells.
Blood Type Compatibility
- Type B blood produces anti-A antibodies, which would react with Type A blood, causing agglutination.
- Type O blood produces both anti-A and anti-B antibodies, making it incompatible with Type A, Type B, or Type AB blood.
- Type AB blood does not produce anti-A or anti-B antibodies, making it compatible with all blood types.
Universal Donor and Universal Recipient
- Type O blood can donate blood to any blood type, making it the universal donor, as it lacks A and B antigens.
- Type AB blood can receive blood from any blood type, making it the universal recipient, as it lacks anti-A and anti-B antibodies.
