Document Summary
4 basic digestive processes: digestion, absorption, secretion, motility. Mouth: chews food and mixes it with saliva. Salivary glands: produces saliva, which contains a starch-digesting enzyme. Stomach: churns and mixes food; secrets acid and protein-digesting enzymes. Liver: makes bile, which aids in digestion and absorption of f at. Pancreas: releases bicarbonate to neutralize intestinal contents; produces enzymes that digest carbohydrates, proteins and fat. Gallbladder: stores bile and releases it into the small intestines when needed. Small intestines: completes digestion; absorbs nutrients into blood of lymph. Large intestines: absorbs water and some vitamins and minerals; home to intestinal bacteria; passes waste material. Anus: opens to allow waste to leave the body. Digestion: process of breaking food into components small enough to be absorbed by the body. Absorption: process of taking substances into the interior of the body. Gastrointestinal tract: hollow tube consisting of mouth -> anus. Transit time: amount of time it takes food to pass the length of the gi tract.
