The purpose of the immune reaction
Essentially, it is to rid the organism of foreign antigens. From birth until death, an organism is surrounded by a host of microorganisms, many of which are dangerous. Using antigen receptors, the immune system continuously screens myriads of substances in the body, discerning among them and mounting an attack against those that are foreign. The end result of a successful immune attack is the destruction of foreign substances and particles, including microbial cells, viruses, various toxins and also tumors. Once destroyed by the immune system, foreign substances or particles or their remains are cleared from the body.
