Digestive System Diagram
Human Digestive System
- The human digestive system includes the following:
- Glands - the salivary glands, and glands in the pancreas that produce digestive juices
- The stomach and small intestine - the sites of digestion
- The liver - produces bile
- Small intestine - the site of absorption of the products of digestion
- Large intestine - the site of water absorption
Tips for drawing an annotated digestive system diagram
- A simple annotated diagram should include some clear features:
- The junctions between each section should be obvious and unobstructed or covered by other parts of your drawing, this includes the following junctions:
- Between the stomach and oesophagus
- Between the stomach and small intestine
- Between the pancreas, small intestine and gall bladder
- The shapes of organs should be approximately true to form e.g. the stomach should be a j-shaped sac
- The liver should be the largest organ represented and located to the left of the stomach
- The diameter of the small intestine needs to be obviously smaller than the diameter of the large intestine
- The junctions between each section should be obvious and unobstructed or covered by other parts of your drawing, this includes the following junctions:

Examiner Tip
Draw your diagrams using a dark pen or pencil to ensure that all components are clear (remember that your paper will be scanned for marking, so your drawing will need to show up clearly after scanning).
