5 Functions
1 Mouth
Salivary amylase initiates digestion of starch
Stomach
Stores food, mixes it with secretions, empties boluses into small intestine
Small Intestine
Digestion and absorption
Pancreatic enzymes, bile
Large Intestine
Absorbs water and electrolytes
2 Liver
Largest internal organ
Makes bile for fat emulsification and digestion
Gallbladder
Concentrates and stores bile
Fat in duodenum causes contraction and release
Pancreas
Exocrine– produces and releases enzymes
Endocrine– releases insulin
6 Effects of Aging on GI System
1 Decreased Appetite
Tooth caries or loss
Decline in taste buds
Decreased sense of smell
Xerostomia
Constipation
Peristalsis slows
Inactivity
Decrease in fiber intake
Inadequate fluid intake
Constipating medications
2 Liver
Decreased ability to metabolize drugs
Gallbladder
Disease increases with age
Decreased Intake
Economic constraints
Immobility
