Exercise 9 Flashcards
What antibody(ies) will be present or absent in the blood plasma of each blood type?
Type A – has anti-B antibody in the plasma of the blood.
Type B – has anti-A antibody in the plasma of the blood.
Type AB – has no antibodies in the plasma of the blood.
Type O – has both anti-A and anti-B antibodies in the plasma of the blood.
What happens to the red blood cells of a recipient if the blood they are receiving from a donor is incompatible with their own blood type?
- If blood types are incompatible, agglutination or clumping of red blood cells will occur.
What would happen if Type A blood was transfused into a person with Type AB blood? Explain your answer.
person with Type AB blood has no antibodies in the plasma of their blood. Therefore, Type AB individuals can receive blood from any Blood Type as they have no antibodies to attack the antigens on the rbc’s of the transfused blood. This explains why Type AB individuals are referred to as universal recipients.
What is the Rh factor? What do the terms Rh+ and Rh- mean?
The Rh factor is another identified antigen on the red blood cell. The term Rh+ means an individual has this antigen, the term Rh- means an individual does not have this antigen on its red blood cell. 85% of the population is Rh+ and 15% of the population is Rh-.
What is the concern when a pregnant woman’s blood is Rh- and the baby’s blood is Rh+?
If a pregnant woman is Rh-, it means that she has anti-Rh antibodies in the plasma of her blood if she has come into contact with Rh+ blood. If during pregnancy or birth the baby’s blood, which has the Rh antigen on its red blood cell, comes in contact with the mother’s blood, agglutination will occur. The mother’s anti Rh antibodies will attack the babies Rh antigens. This is called hemolytic disease of the newborn.
What are the four ABO blood types and what antigen(s) will be found on the red blood cells of each blood type
The four ABO blood types are:
Type A – has an ‘A’ antigen on the red blood cell.
Type B – has a ‘B’ antigen of the red blood cell.
Type AB – has both an ‘A’ and ‘B’ antigen of the red blood cell
Type O – has no antigens on the red blood cell.
