The three organs that make the digestive system work are the pancreas, the liver and the gall bladder.

The pancreas creates juice that contains enzymes, which aid the
breakdown of food into molecules small enough to be absorbed by the
body. It synthesises insulin and releases it into the bloodstream.

The liver is the largest of the body's internal organs. Nutrients and other substances - inlcuding toxins - enter the liver from the digestive tract. The liver creates bile, which breaks down fat, and breaks down toxins and other substances (unless there are too many to cope with, in which case damage can occur.) It then releases glycogen and other substances into the blood.


The gallbladder stores the bile that the liver makes. The gallbladder concentrates the bile and discharges it into the bile duct.
