The liver and pancreas produce digestive juices that help break down food. Digestion works by moving food through the
gastrointestinal tract (GI tract). Digestion begins with chewing in the mouth and ends in the small intestine. As food passes
through the GI tract, it mixes with digestive juices that are produced by the liver and pancreas. Larger molecules of food are
broken down into smaller molecules. These smaller molecules are absorbed through the walls of the small intestine into the
bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out
of the body at the anus as solid matter.
