Lecture Test 2 Part Two Flashcards
What is the ABO system?
system of grouping blood according to the presence or absence of antigen A and antigen B
Those who have antigen A on the surface of their RBCs have
type A blood
Those who have antigen B on the surface of their RBCs have
type B blood
Those who have antigen A and antigen B on the surface of their RBCs have
type AB blood
Those with no antigens on the surface of their RBCs have
type O blood
In order to have type O blood:
both parents have to have type O blood
There are ______ in the plasma that will react with the antigens of other blood types.
antibodies
When incompatible bloods are mixed together,
a transfusion reaction occurs
what is a transfusion reaction?
RBCs burst releasing hemoglobin into the blood
what is hemolysis?
bursting of red blood cells
The main reaction to compare when evaluating matches is
donor antigen and recipient antibody
Type A blood has
A antigens
anti B antibodies
Type B blood has
B antigens
anti A antibodies
Type AB blood has
A and B antigens
no antibodies
Type O blood has
no antigens
anti A and anti B antibodies
Who is the universal recipient
AB
Who is the universal donor?
O
Humans are born with
ABO antigens but develop appropriate antibodies
What is the Rh system?
A blood typing first discovered in the rhesus monkey
Those who have Rh antigens on their RBCs
are Rh+
Those who lack Rh antigens on their RBCs
are Rh -
Which typing is most popular on the Rh scale?
Rh+
To be Rh-,
both parents must contribute a Rh gene
Normally there are no ___________ in the blood of Rh - people
anti Rh antibodies
