ABO Blood Types Flashcards
Molecule on the surface of cells and on pathogens
~Identification system, stimulates the formation of an antibody.
Antigens (Ag)
Protein that recognizes foreign substance and acts to neutralize or destroy
~Produced by the recipient and act on invading antigen
Antibodies (Ab)
In humans, blood types can be classified in two ways based on the antigen markers found on the membranes of each RBC. What are the two groups/ways?
ABO Groupings and RH Groupings
Our White blood cells produce __________ against other blood types.
Antibodies
Red blood cells present different antigen based on our ___
DNA
Blood type A = Antigen _
A
Blood type B = Antigen _
B
Blood type AB = Antigen _ and _
A and B
Blood type O = __ Antigen
No Antigen
Blood type A = _ Antibody
B
Blood type B = _ Antibody
A
Blood type AB = __ Antibodies
No Antibodies
Blood type O = _ and _ Antibodies
A and B Antibodies
Inherited antigens (like ABO blood types)
Rhesus Grouping
Rh- humans have no natural antibodies against Rh factor, but antibodies can be produced if they are exposed to the Rh factor during..
blood transfusion, or pregnancy
Rh- individuals may donate to Rh+ individuals, but..
they cannot receive Rh+ blood
Which blood type is known as the Universal Recipient?
AB+
~Has all 3 types of antigens, no antibodies
~Can receive blood from any donor but can only donate to blood type AB+
Which blood type is known as the Universal Donor?
O-
~Has no antigens
~Can donate blood to all blood types but can only receive from blood type O-
When antigens and antibodies react with one another the blood clumps together, what is another term used to describe this clumping?
Agglutination
What does Agglutination indicate?
Rejection by blood cells
