pathogens may enter the body and cause illness.
Explanation: A weakened immune system cannot mount effective defenses (phagocytes, antibodies, etc.), so invading pathogens are more likely to establish infection and cause disease. The other choices are incorrect: phagocytes fight infection (they don't cause it), normal cells crowding out unhealthy cells would be beneficial, and antibody production would be decreased, not increased.
