Document Summary

Pancreas secretion of enzymes and bicarbonate; also has non- Enzymes digest carbohydrates, fats, proteins, and nucleic. Bicarbonate neutralize hcl entering the small intestine from. Liver secretion of bile; many other non-digestive functions. Organic waste products and trace metals elimination in. Gallbladder store and concentrate bile between meals. Small intestine digestion and absorption of most substances; mixing and propulsion of contents. Salt and water maintain fluidity of luminal contents. Large intestine (colon) storage and concentration of undigested matter; mixing and propulsion of contents acids the stomach the stomach feces. General features (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Alkaline secretions from pancreas and liver quickly neutralize acid chyme in upper duodenum. Most enzymatic digestion of lipids and carbohydrates, and most completion of protein digestion takes place in the duodenum. Absorption of the products of digestion mostly occurs in the. The ileum provides additional length and reserve capacity for duodenum and jejunum absorption, if needed.
