Quizplus · Accepted Answer

Innate immunity refers to the non-specific defense mechanisms that come into play immediately or within hours of an antigen's appearance in the body. These mechanisms include physical barriers like stomach pH, cellular defenses like natural killer cells, and physiological responses like fever. B lymphocytes, however, are part of the adaptive immune system, which is specific and requires time to respond to specific antigens.
