Is there an important part of the system not shown on the diagram?
D
 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)
 Use
p30 to create a flow chart identifying
the different parts of the digestive system
and how they are specialised for their
function
 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
 Small

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
