Drag and drop the boxes into the correct order.



  • The external intercostal muscles and diaphragm contract
  • Air is exhaled into the atmosphere to this area of low pressure from an area of relatively high pressure (the lungs)
  • Air is inhaled into the lungs
  • The volume in the thoracic cavity increases as air is inhaled into the lungs

  • 2. Expiration at rest:
  • This causes the rib cage to move upwards and outwards
  • The volume in the thoracic cavity decreases as air is exhaled into the atmosphere
  • 1. Inspiration at rest:
  • The external intercostal muscles and diaphragm relax
  • This causes the ribs to move downwards and inwards
