2. Starter: Identify The Human Digestive System
Letter
Structure A B C D E F
Oesophagus B
Stomach D C
Small Intestine
Large Intestine
Rectum E
Anus F
Is there an important part of the system not shown on the diagram?

3. Success Criteria
State where food enters and leaves the tissues (Grade E)
Describe how food molecules are absorbed (Grade C)
Explain how the small intestine is adapted for efficient adsorption (Grade A)

4. Specialised parts of the digestive system
Use p30 to create a flow chart identifying the different parts of the digestive system and how they are specialised for their function

5. Specialised parts of the digestive system
Mouth – salivary glands (moisten food and contain enzymes)
Oesophagus – peristalsis
Stomach – physical and chemical digestion
Liver bile
Pancreas  enzymes
Small intestine(first part) enzymes
Small intestine (second part) absorption
Large intestine  absorbs water

6. HIGHER: Villi Small intestine adaptations
Villi to increase surface area
Thin wall
Good blood supply

7. Life of a Chip: Extended Writing

8. Peer Assessment: ?/5 Correct order of the digestive system
Included both chemical and physical digestion
Included the role of both amylase and carbohydrase in the break down of starch
Included the role of bile
Include the breakdown of fat (Liapse)
Include absorption of smaller molecules into blood

9. Success Criteria
State where food enters and leaves the tissues (Grade E)
Describe how food molecules are absorbed (Grade C)
Explain how the small intestine is adapted for efficient adsorption (Grade A)
