Human Digestive System: A Visual Explainer
A single-glance diagram tracing the complete path of food through the human alimentary canal, from the mouth to the anus.
📌 Revision Pointers
Sequence: Mouth → Oesophagus → Stomach → Duodenum → Jejunum & Ileum → Large Intestine → Anus
Liver/Gallbladder (bile) and Pancreas (digestive enzymes) both empty into the duodenum, not the stomach
Digestion finishes in the small intestine; the large intestine only absorbs water and compacts residue into faeces
The full digestive pathway — mouth, oesophagus, stomach, duodenum, jejunum & ileum, large intestine and anus — shown as one clean labelled flowchart, with the liver, gallbladder and pancreas marked as accessory glands feeding into the duodenum.
💭 Conclusion
Sequence and gland-matching diagram questions on the alimentary canal are a recurring UPSC Prelims favourite.
