Questions from this subtopic
Each one with the model answer underneath.
- 1
What are the two kinds of digestion?
Model answer
Digestion is mechanical, where food is physically broken into smaller pieces, and chemical, where enzymes break large molecules into small soluble ones.
- 2
What happens to food in the mouth?
Model answer
In the mouth the teeth chew food into smaller pieces and the tongue mixes it with saliva to form a bolus that can be swallowed.
- 3
What does saliva contain, and what does it do?
Model answer
Saliva contains water, mucus and the enzyme amylase, which lubricates the food and begins the breakdown of starch into maltose.
- 4
Name the three pairs of salivary glands.
Model answer
The three pairs of salivary glands are the parotid, the submandibular and the sublingual glands.
- 5
How does food travel down the oesophagus?
Model answer
Waves of muscular contraction called peristalsis squeeze food down the oesophagus into the stomach.
