Bacteria are associated with all areas of the human body from the skin to the genitourinary, respiratory and gastrointestinal (GI) tracts. The GI tract is the most heavily populated, with the majority of the total bacterial population of humans residing therein. The GI tract has evolved to become a functional organ comprising anatomically distinct areas. The digestive process starts in the oral cavity, then moves through the stomach, small and large intestine and finally the rectum. This chapter summarizes the functions of the human gastrointestinal tract. A main function of the GI microbiota is modulation of the immune system. The chapter focues on the factors influencing composition of the microbiota.
