15 Questions
What happens when mismatched blood is infused during a transfusion?
Transfusion reactions occur, causing diminished oxygen-carrying capacity and clumped cells that impede blood flow.
What is the role of anti-A and anti-B agglutinins in the body?
They initiate the development of antibodies against type A and B antigens.
Why is it essential to ensure compatibility between the donor's and recipient's blood types during transfusions?
To prevent agglutination of RBCs, which can lead to transfusion reactions and impaired oxygen-carrying capacity.
What is the significance of the universal donor and universal recipient in blood transfusions?
The universal donor has type O negative blood, which can be transfused to anyone, while the universal recipient has type AB positive blood, which can receive blood from anyone.
How do type A and B antigens enter the body?
Through food, bacteria, and other sources.
What is the consequence of transfusing incompatible blood groups during a blood transfusion?
Candid health problems
What is the role of antigens in the ABO blood group system?
They are present on the surface of red blood cells and trigger an immune response
What is the origin of the antibodies in plasma?
Produced by the immune system in response to the presence of antigens
Why is it crucial to determine an individual's ABO blood group before a blood transfusion?
To prevent an immune response and ensure compatibility
What is the purpose of antibodies in the ABO blood group system?
To react with antigens on the surface of red blood cells
What is the primary factor that determines an individual's blood group?
antigens (agglutinogens) on the surface of RBCs
What two blood groups are commonly used in blood transfusion compatibility?
ABO and Rhesus
What is the role of antigens in blood group determination?
Antigens trigger an immune response, causing the production of antibodies.
Why is it important to determine an individual's blood group before a blood transfusion?
To ensure compatibility and prevent an immune response
What is the genetic basis of blood type inheritance?
The genes that code for the antigens on the surface of RBCs
This quiz covers the basics of blood types, including ABO blood groups, agglutination reactions, and the importance of matching blood types during transfusions. Learn about the different types of blood and how they interact with each other.
