Digestive system

The digestive system function is to degrade food into smaller and smaller compounds, until they can be absorbed into the body and used as energy. It consists of a series of gastrointestinal tract organs and accessory digestive organs.

The digestive system organs spread from the mouth to the anal canal. So it’s actually a tube consisting of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anal canal. Accessory digestive organs assist with the mechanical and chemical food breakdown, these are the tongue, salivary glands, pancreas, liver and gallbladder.
