Which body system helps the body resist disease?

Explanation:
The immune system defends the body against pathogens and disease. It uses barriers like skin and mucous membranes, plus specialized cells and molecules that detect and attack invaders. Innate immunity provides quick, nonspecific defense with phagocytes, natural killer cells, inflammation, and fever. Adaptive immunity adds a targeted response through T cells and B cells, producing antibodies and memory for future protection. Other systems support immunity by transporting immune cells or filtering pathogens, but the system that directly resists disease is the immune system.
