Blood Types
Blood Types
•Four human blood types or

•Individuals needing a
blood transfusion must be
_________typed.

People with type O blood can donate to all other
types and are called universal ________. Individuals
with type AB are called universal __________.
11
Individuals receiving incompatible blood during a
Rh Factor
Rh
Factor
transfusion will have agglutination or clumping
of the blood which can be fatal.
In addition to the blood type, there is a positive or
negative element found in the blood.
•Rh positive blood contains an antigen first
identified in the ________ monkeys.
•Rh negative blood does not contain the antigen.
The Rh factor is very important during ________
because a mother that is Rh negative carrying a
Rh positive fetus will develop _________ to fight Rh
positive blood cells with future pregnancies.
12
