The alimentary tract of the digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus. Associated with the alimentary tract are the following accessory organs: salivary glands, liver, gallbladder, and pancreas.
These organs include the pancreas, the liver and the gallbladder, as well as several different glands. Without the aid of the accessory organs of the digestive system, digestion would not occur within the stomach or small intestine. Each organ and gland plays a very specific role in the system. In this way, they are as essential to the process as the main organs where digestion actually takes place.
