D Correct answer
Explanation

The immune system identifies and destroys pathogens before infections become severe. When immune function is compromised, even minor gut infections can progress to serious conditions like dysentery with bloody diarrhea, as the body cannot control the infection. The circulatory, respiratory, and nervous systems are not primarily responsible for fighting infections.
