                    In addition to all this, the immune system has a special
                 function that assists the phagocytes, by developing antibodies
                 against most foreign bodies such as bacteria. These antibodies
                 adhere to the bacterial membranes and make them susceptible
                 to phagocytosis. Amazingly, the antibody does this by binding






                                             Macrophages attack enemy cells they
                                             recognize by their surfaces and display
                                             parts of enemies on themselves. This
                                             signal announces the presence of an
                                             enemy in the body and initiates the
                                             immune response.
