Understanding Blood Groups
Blood groups are classified based on the presence or absence of specific antigens and antibodies in the blood. The ABO blood group system is one of the most significant classifications.
Blood Group A Characteristics
- Individuals with blood group A have antigen-A on the surface of their red blood cells.
- They produce antibody-B in their plasma, which reacts against any B antigens.
Key Components of Blood Group A
- Antigen-A:
- This is a specific protein found on the surface of red blood cells.
- It is responsible for defining the blood group as A.
- Antibody-B:
- This is an immune protein produced by the body.
- It acts against B antigens, preventing the body from accepting B blood.
Reason for Antibody Production
- The immune system identifies foreign substances (antigens) and produces antibodies to neutralize them.
- Since blood group A does not have B antigens, the presence of antibody-B protects the individual from receiving incompatible blood types, particularly type B or AB.
Conclusion
Thus, for a person with blood group A, the correct configuration is:
- Antigen-A and Antibody-B (Option A).
This understanding is crucial for safe blood transfusions and organ donations, ensuring compatibility and reducing the risk of immune reactions.
