                                 THE MIRACLE OF THE IMMUNE SYSTEM


              is a threat to their own housing site. Since they do not want to be dis-
              placed by the invaders, they fight a fierce battle against them. We can
              think of these micro-organisms as "professional soldiers" fighting for the
              body. They try to protect the site they live in for their own benefit. In so
              doing, they complement the fully equipped army in our body.
                   How do these "professional soldiers" settle in our bodies?
                   The human embryo has met no enemy during the gestation period in
              the mother’s womb. Following the birth of the child, it makes contact with

              the environment, and numerous microbes are introduced to the child
              through the intake of food and by way of the respiratory tract. Some of
              these microbes die right away, while others are discharged before having
              the chance to settle down in the body. Some, however, settle in various
              parts of the body such as the skin, skin ridges, mouth, nose, eyes, upper
              respiratory tract, digestive tract, and genital organs. These microbes form
              permanent colonies at these locations and constitute the microbial flora of
              the human body.




























              There are hundreds of bacteria in the world. In the above picture, you can see
              only a few of them.
