  8. What is the function of the nose?
    To warm and clean the air
  9. What is the function of the epiglottis?
    To stop food from going down the wrong way
  10. What is the function of the trachea (windpipe)?
    To carry air from the nose to the bronchus
  11. What is the function of the rings of cartilage?
    To give strength and support to the trachea (windpipe) and keep it open
  12. What is the function of the bronchus?
    To allow air to flow into and out of the lungs
  13. What is the function of the bronchioles?
    To carry air to and from the air sacs (alveoli)
  14. What is the function of the alveoli (air sacs)?
    To put oxygen into the blood and remove carbon dioxide from the blood
  15. Explain what occurs during gaseous exchange.
    Oxygen is put into the bbloodstream and carbon dioxide is removed from the blood and released from the body through the nose
  16. How are the alveoli adapted for gaseous exchange?
    The walls are very thin so the gases can get through very quickly

    There are so many alveoli it provides a large surface area for gaseous exchange

    Each alveoli is covered in capillaries so it allows for a quick exchange of oxygen and carbon dioxide
