The basic resistance you are born with is called _________.

• A. Acquired immunity
• B. Adaptive immunity
• C. Innate immunity
• D. General immunity

Answer: (C)

Innate immunity is the body's built-in, non-specific defense present from birth. It provides immediate protection against many pathogens without needing prior exposure. It includes physical barriers like skin and mucous membranes, chemical barriers such as stomach acid, and cellular defenses like neutrophils and macrophages, natural killer cells, and the complement system, plus the inflammatory response. Because these defenses respond in the same way to a wide range of invaders and don’t learn from previous encounters, they are the initial shield you’re born with. In contrast, acquired or adaptive immunity develops after exposure to a specific pathogen or vaccine, is tailored to particular antigens, and creates immunological memory for faster responses in the future. The term general immunity isn’t a recognized description for this context.
