Syndrome (IBS),bowel disease (IBD).

The food and liquid follow the tract in orderly fashion being moved along by these involuntary movements. The first area that the food and liquid pass through is the esophagus, then the stomach. The stomach has 3 functions to complete in the digestive process. The stomach stores, mixes and empties food and liquid. After the stomach completes these 3 functions it empties the contents into the small intestine. The juices of the pancreas, liver, and intestine are used to further digest the food, and then the contents of the small intestine are mixed and pushed further where it is further digested. The digested nutrients are absorbed through the intestine walls and the waste products (parts not used by the body), including undigested parts of food (fiber, and older cells shed by the mucosa) then move into the colon. These products remain in the colon for one or two days until they are expelled by a bowel movement.

A few of the common digestive system disorders include: Celiac disease, Irritable bowel syndrome (IBS), Gastritis and peptic ulcers, and Inflammatory bowel disease (IBD).
