Digestion begins in the mouth, where food and liquids are taken in, and is completed in the small intestine.rgans that help with digestion, but are not part of the digestive tract, include the following: Tongue. Glands in the mouth that make saliva. Pancreas. Liver. Gallbladder. Parts of other organ systems, such as nerves and blood, also play a major role in the digestive process.
