The immune system consists of specialized cells and organs that protect an organism from outside biological effects and from inside changes. If the immune system is functioning properly, it protects the body against microbial infections, destroying cancer cells and foreign substances. If the immune system weakens, it allows pathogens to grow and flourish. Organs of the immune system Central (primary) lymphoid organs These are the sites of maturation of the lymphocytes 1-Bone...
