Moving on… We learnt about the incredible Digestive System by watching a live demonstration in class. We used a

  • Papaya to represent as the general food we take in each day
  • A knife which chopped up the papaya was our representation of all the types of teeth within our oral cavity which chops down the food.
  • An umbrella cover played the role of the Food Pipe/Esophagus which transports the food down into our stomach through the process of peristalsis.
  • A blender was used to demonstrate the process of  churning and grinding that takes place inside the stomach with the help of acids and bile.
  • A stocking and sock represented the two intestines
  • There were two bowls to represent our stomach and  the output which is the end product of the whole process.
