Concept map on the IMMUNE SYSTEM. This concept map illustrates the functioning of the immune system, the set of mechanisms that defend the body against foreign or pathogenic agents. It shows the natural defense barriers, such as skin, saliva, and mucus, and the non-specific responses such as phagocytosis. It also explains the specific immune response, which produces targeted antibodies against a single antigen. Through immunological memory, the body recognizes and reacts more quickly to future infections.
