Accepted Answer

Innate immunity is the first line of defense against pathogens and it reacts to a wide variety of pathogens without the need for prior exposure or vaccination. It is non-specific and includes physical barriers (e.g. skin), chemical barriers (e.g. stomach acid), and cellular defenses (e.g. phagocytes).
