ABO blood types Flashcards
1
Q
Antigen (Ag)
A
Protein that stimulates the formation of an antibody
2
Q
Antibody (Ab)
A
- Protein formed within the blood that reacts with an antigen
- Produced by recipient and act on invading antigens
- Cause agglutination (clumping) by attaching to antigen
3
Q
Agglutination
A
- When blood is agglutinated, it cant pass through tiny capillaries
- Clogs the capillaries and prevents delivery of oxygen and nutrients
4
Q
Blood type A
A
- Antigen A
- Antibody B
5
Q
Blood type B
A
- Antigen B
- Antibody A
6
Q
Blood type AB
A
- Antigen A and B
- No antibodies
- Universal receiver
- Can receive any blood from any donor because it posses both antigens A and B
- Can only donate blood to type AB
7
Q
Blood type O
A
- No antigens so AB wont fight off type O
- Antibodies A and B
- Universal donor
- Can donate to all blood types
- Can only accept blood from other blood type O
8
Q
Glycoproteins (aka antigens)
A
Located on some RBC and serves as markers that identify blood as different blood types
9
Q
Rhesus factor
A
- Inherited Antigens
- Individuals w/ rhesus factor are Rh+
- Individuals w/out rhesus factor are RH-
- Rh- individuals may donate to RH+ individuals but cant receive RH+ blood
- No natural antibodies against Rh factor but can be produced by transfusion
10
Q
Erythroblastosis Fetalis
A
- If baby inherits Rh+ factor, Erythroblastosis Fetalis can occur
- First child is okay because blood of mother and baby are separated by placenta
