Question
A person whose blood type is "A +" has which antigens on their red blood cells?
- Rh factor
- O
- B
- A
Multiple select question.
Solution
To determine the blood type antigens present on a person with the blood type "A +", we can analyze the components of blood type classification.
Breakdown of Blood Type Determination
-
ABO System: Blood types are classified based on the presence or absence of antigens A and B.
- Type A: Has A antigens on the surface of red blood cells.
- Type B: Has B antigens.
- Type AB: Has both A and B antigens.
- Type O: Has neither A nor B antigens.
-
Rh Factor: The Rh factor (Rhesus factor) indicates the presence (+) or absence (-) of another antigen called the D antigen.
- Rh+: D antigen is present.
- Rh-: D antigen is absent.
Answer
In the case of a person with blood type "A +":
- They have A antigens.
- They have the Rh (D) antigen.
Final Answer
Thus, the correct selections are:
- A antigens
- Rh factor
O and B antigens are absent in a person with type A blood.
