They are a type of antigen that some people carry on their red blood cells. They are called "rhesus" because they were initially identified and studied on the red blood cells of rhesus monkeys, then were later also found in humans. If a person has Rh+ blood type they have this antigen, if a person has Rh- blood type they do not.
They are important in blood transfusions in that a person with Rh+ blood type can receive either Rh+ or Rh- blood with no problems, but a person with Rh- blood type can only receive Rh- blood (Rh+ blood could kill him when antibodies from his immune system attack the rhesus antigen, causing massive blood clotting).
They are important in pregnancy in that a woman with Rh- blood type has a much higher chance of miscarriage if her baby has Rh+ blood type.
Note: there are roughly 30 different classes of blood type antigens, not just the familiar A, B, and Rh antigens. Most however are very rare.

Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Where are the blood antigens A B Rh located?
The blood antigens A, B, and Rh are located on the membrane of the red blood cell. These antigens are hereditary.
A person who is B positive will have?
B antigens, antibodies to A, and Rh antigens
Of the antigens in the rh group?
The most important Rh antigen is the D antigen.
If red blood cells lack RH antigens the blood is called?
rh-negative
How does the Rh factor differ from A B and O antigens?
The Rh factor exhibits normal dominant/recessive patterns. In contrast, the ABO antigens express codominance.
Rh antigen is also called?
There are about 45 different Rh antigens, the most important of which is the D-antigen.
What is the serum used to prevent sensitization to rh antigens?
RhoGAM
Substance that determines blood types is found in the membrane of red blood cells?
Antigens. Your blood type depends if you have A, B, AB, or none of those antigens (O). These antigens can also be positive or negative depending on whether you have the Rh antigen, or Rh factor.
What antigens are expressed if a person is blood type AB negative?
My daughter is AB negative , I am B positive and her dad it A negative
How many types of antigens on the erythrocytes?
There are two types:A, B, O and AB group.Rh factor, either it was there (Rh+) on not there (Rh-)
The immune serum used to prevent maternal sensitization to Rh antigens is?
RhoGAM
