The digestive system is composed of the gastrointestinal tract—commonly referred to as the GI tract or digestive tract—as well as the liver, pancreas, and gallbladder.

The mouth, esophagus, stomach, small intestine, large intestine, and anus are the hollow organs that comprise the GI tract. The liver, pancreas, and gallbladder are the digestive system’s solid organs (NIDDK, 2019).
