Detailed explanation-1: -White blood cells protect your body against infection. As your white blood cells travel through your bloodstream and tissues, they locate the site of an infection and act as an army general to notify other white blood cells of their location to help defend your body from an attack of an unknown organism.

Antibodies attach to red blood cells and travel throughout the body, fighting germs and other foreign substances that should not be there. In AIHA, the body makes antibodies that attack the red blood cells because they think they are foreign or unwanted substances.
