Flashcards in Blood types Deck (15):
1

agglutination

clumping of red blood cells in response to a reaction btwn an antibody and an antigen

2

Antigens

chemical that stimulates cells to produce antibodies

3

Antibodies

a protein that reacts against a specific antigen

4

Blood type A
-antigen? -antibody?

Antigen: A
Antibody: anti-B

5

Blood type B
-antigen? -antibody?

Antigen: B
Antibody: anti-A

6

Blood type AB
-antigen? -antibody?

Antigen: A and B
Antibody: Neither anti-A nor anti-B

7

Blood type O
-antigen? -antibody?

Antigen: Neither A nor B
Antibody: Both anti-A and anti-B

8

Rh blood group
-caused by?
-present vs absent?
percent negative?
-how inherited?

caused by Rh antigen D in blood
-if present -> Rh-positive
-if missing -> Rh-negative
only 15% are Rh negative
inherited trait w/ blood type

9

Rh factor and pregnancy (5 steps)

1)Rh- woman and Rh+ man conceive a child
2)Rh- woman w/ Rh+ fetus
3)Cells from Rh+ fetus enter woman's bloodstream
4)Woman becomes sensitized - antibodies form to fight Rh+ blood cells
5)In the next Rh + pregnancy, maternal antibodies attack fetal red blood cells
