The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liverpancreasand gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
The digested organs that make up the GI tract are the mouth, esophagusstomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts.
