Immunity can be defined as a complex biological system endowed with the capacity to recognize and tolerate whatever belongs to the self, and to recognize and reject what is foreign. The adaptive immune system works to protect and heal the body when the innate immune system fails. It provides the body with the ability to recognize and remember specific pathogens through their antigens. The adaptive immune system, also referred as the acquired immune system, is a subsystem of the immune system that is composed of specialized, systemic cells and processes that eliminate pathogens or prevent their growth. The acquired immune system is one of the two main immunity strategies found in vertebrates. The presentation gives in-depth knowledge on the topic.
