Read the complete pathway
- Mouth. Chewing and saliva begin processing; salivary amylase acts on starch.
- Oesophagus. Peristalsis propels the bolus.
- Stomach. Mixing, acid and pepsin support protein digestion.
- Duodenum. Bile and pancreatic secretions enter.
- Jejunum and ileum. Digestion continues and most nutrients are absorbed.
- Colon, rectum and anus. Water recovery, storage and elimination complete the route.
