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!
