Shamim Ansary:
Rh factor

Rh factor is a protein called an antigen that is found on the red blood cells of most people. (An antigen is any substance that the body considers "foreign" and thus stimulates the body to produce antibodies against it.) Rh factor, like the blood types A, B, and O, is inherited from one's parents. A simple blood test can determine blood type, including the presence of the Rh factor. About 85 percent of white Americans and 95 percent of African Americans have the Rh factor and are known as Rh-positive. Those without the Rh factor are Rh-negative.

Shamim Ansary:
BLOOD TYPING

1901 - Austrian Karl Landsteiner discovered human blood groups

Blood Type is Controlled by 3 Alleles
Alleles: A, B, O
A & B are codominant
O is recessive

Shamim Ansary:
Blood Transfusions

Blood that has antibodies on it that is not recognized by the body will be attacked by your immune system
O is the Universal Donor because a person with this type of blood does not have antigens on the surface of the blood cells - hence will not cause an immune reaction in the patient.
AB is the universal Acceptor because this person will not have an immune reaction to A, B, AB, or O
