An elderly male patient with stomach cancer recently had a feeding tube inserted into his alimentary
canal to bypass the esophagus, stomach and duodenum. He had his gall bladder
removed several years ago.
The Digestive Tract:
Stomach: holding sac where chemical and mechanical digestion continues on the bolus; initiates the chemical digestion of protein and fat.
-
Large Intestine: chemical digestion; absorbs water and electrolytes from the remaining digested material and compacts it into feces.
-
Accessory Digestive Tract: assist in the digestion of food and produce secretions that empty into the GI Tract.
Gastrointestinal Tract: mechanical and chemical digestion, similar to the ACT, accomplishes swallowing which moves the bolus down to stomach which then turns to chyme, and finally feces.
Small Intestine: finishes chemical digestion & is responsible for absorbing most of the nutrients from food.
Duodenum
Duodenojejunal Flexure
Jejunum

Ingestion, motility, secretion, and mechanical digestion from the upper gastrointestinal and accessory digestive tract do not occur.
