How can I relate the Rh incompatibility to other blood cells?

Unclear question. It is not feasible to answer your question as there is no incompatibility between a person's red cells and other cells.
Not sure of question. Rh incompatibility is a red blood cell phenomenon. Typically a mom has no rh antigen, therefore will make an rh-antibody if exposed. This causes rbc breakdown in rh-positive infants born to these mothers. The same thing can occur with platelets and neutrophils. There is an antigen discrepancy, which causes mom to produce antibody, which causes cell destruction.
