Summary Introduction
Introduction: The immune system provides two types of immunity, one is innate immunity which is found from birth, and the other is adaptive immunity, which is acquired in a lifetime when exposed to pathogens. Innate immunity is non-specific and can act on a set of antigens while the adaptive immunity is specific to a particular antigen. Adaptive immunity creates immunological memory cells.
