What types of tissues build the digestive system?

The digestive system isn't really made up of a specific type of tissues, but rather composed of different organs within the system. The digestive system is made up of the alimentary canal and the other abdominal organs that play a part in digestion, such as the liver and pancreas. The alimentary canal (also called the digestive tract) is the long tube of organs - including the esophagus, the stomach, and the intestines.
