Let me share with you a difference between ingestion and digestion.
| Aspect | Ingestion | Digestion |

| Occurrence | Primarily occurs in the mouth | Primarily occurs in the stomach and small intestine |
| Mechanism | Involves the mechanical and initial chemical breakdown of food through biting, chewing, and swallowing | Involves enzymatic and chemical processes that break down large molecules into smaller ones |
| Enzymes involvement | Limited involvement of digestive enzymes | Various digestive enzymes, such as amylases, proteases and lipases |
| Duration | A relatively quick process | A more prolonged process |
