Summary

The gastrointestinal (GI) tract extends from the mouth to the anus. It represents a series of organs with specialised roles, motor patterns and secretory functions. Its primary purpose is the absorption of water and nutrients. Food is moved along its length and mixed with secretions that aid digestion. Nutrients are absorbed across the gut wall and waste products and indigestible residue excreted as faeces.
