What happens if a person receives a blood transfusion with foreign red blood cell antigens?

What does the word 'agglutination' literally mean in its Latin roots?

Which of the following statements about red blood cell antigens is true?

Which of the following accurately describes erythrocytes?

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.
