Which term describes the body's ability to resist and fight pathogens?

• A. Bacteria
• B. Pathogenic Disease
• C. Immunity
• D. Direct Transmission

Answer: (C)

Immunity is the body's ability to resist and fight pathogens. It involves defenses from physical barriers like the skin to immune cells such as white blood cells and antibodies that target invaders. The system works in stages: innate immunity provides immediate, nonselective defense, while adaptive immunity develops specific responses and memory after exposure. This helps protect you during procedures and is supported by good hygiene and aseptic technique. The other terms describe what pathogens are (bacteria), the illness they cause (pathogenic disease), or how they spread (direct transmission), not the body's defense itself.
