Effects of Aging on the Digestive System

With age, the pancreas decreases in overall weight, and some tissue is replaced by scarring (fibrosis). However, these changes do not decrease the ability of the pancreas to produce digestive enzymes and sodium bicarbonate. As the liver and gallbladder age, a number of structural and microscopic changes occur (see Effects of Aging on the Liver).
