Year 7 students in science enjoyed carrying out research into the various stages of the digestive process. They were then each given a role in this process and together as a class demonstrated what happens at each stage:
- food going into the mouth.
- teeth and their role in breaking down food particles.
- enzymes and saliva adding to food to aid digestion.
- the tongue and its role in rolling the food around in the mouth.
- food transferring from the mouth to the stomach via the oesophagus.
- more enzymes and acid that’s produced in the stomach.
- the stomach being muscular and when it contracts it pummels the food to help with breaking down larger molecules into smaller molecules.
- the passage of food from the stomach to the small intestine.
- the bloodstream absorbing the nutrients from the small intestine.
- digested food moving from the small intestine to the large intestine and the fact that excess water will be absorbed in the large intestine.
- Lastly the undigested food ending up in the toilet!
