The digestive system consists of a long tube extending from the mouth to the anus and the accessory structures attached to that tube. The tube has several names, including the GI tract, the gastrointestinal tract, and the alimentary canal. The regions of the GI tract include the mouth, oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine (Figure 10.1). These regions are specialized for certain aspects of digestion. The accessory structures that assist the functions of the GI tract include the salivary glands, liver, gallbladder, and pancreas.
