Answer

Brief Explanations:

The immune system defends against pathogens. A weakened immune system can't stop pathogens from entering and causing illness. Phagocytes are part of the immune - defense, normal cells don't crowd out unhealthy cells in this context, and antibody production would be decreased or impaired in a weakened immune system, not increased.

Answer:

pathogens may enter the body and cause illness.
