Digestive juices are produced by two solid organs: the liver and the pancreas, and they travel through small tubes to the intestine. Other organ systems (such as nerves and blood) also play a function in the digestive system.

The bacteria in your gastrointestinal tract, often known as gut flora or microbiome, aid digestion. Parts of your nervous and circulatory systems also play a role. Nerves, hormones, germs, blood, and the organs of your digestive system work together to digest the meals and drinks you consume every day.
