How do red blood cells enter the circulation of another person?

The red blood cells (RBCs) from one person may enter into the circulation of another person in two different ways, either by a blood transfusion or by pregnancy. The RBCs will appear foreign if they contain antigens that are not found on the patient’s own RBCs.
