The Digestive Journey

Science · The Human Body · conceptual

Trace the journey of food through the digestive system: food enters the mouth where teeth break it down and saliva begins digestion, travels down the oesophagus to the stomach, passes through the small intestine where nutrients are absorbed, and waste moves through the large intestine

What mastery looks like

  • List the organs in order: mouth, oesophagus, stomach, small intestine, large intestine
  • Describe what happens at each stage (teeth chew, stomach churns with acid, small intestine absorbs nutrients)
  • State that the small intestine is where most nutrients pass into the blood, and the large intestine removes water from waste

Check your understanding

If The Digestive Journey ate a sandwich, could they describe the journey it takes through their body — from mouth to stomach to intestines?
