Figure shows the human digestive system.

Add each label to the appropriateness of the diagram. Some labels should be written in two places.

Labels to add

• Physical digestion, increases the surface area of food (two places)
• The gall bladder
• Amylase is secreted (two places)
• Amylase acts on starch (two places)
• Lipase breaks down fats
• Absorption happens
• Secretes a liquid with a low pH, which kills bacteria
• Protease is secreted (two places)
