Lesson Title: Today we are learning about
How are the lungs adapted to allow gas exchange?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Gas exchange in humans occurs in the lungs.
  2. Gas enters the mouth and nose and descends down the wind pipe (trachea).
  3. The wind pipe splits into two Bronchi. One Bronchus to each lung.
  4. The Bronchi split into small tubes called Bronchioles.
  5. The Bronchioles lead to the alveoli (air sacs)
  6. Lungs are adapted to speed up gas exchange.
  7. The many Alveoli give the lungs a huge internal surface area.
  8. Alveoli's large surface area allows more particles to travel through at the same time.
  9. Alveoli have good blood supply.
  10. Alveoli's good blood supply maintains the difference in concentration as oxygen is taken away and carbon dioxide delivered quickly.
  11. Alveoli walls are only one cell thick.
  12. Alveoli's one cell thick walls reduces the distance the particles have to travel between the air and the blood.

AFL/Key Questions:
  1. What organ is responsible for gas exchange in humans?
    Gas exchange in humans occurs in the lungs.
  2. How does the air enter the lungs?
    Gas enters the mouth and nose and descends down the wind pipe (trachea).
  3. What does the wind pipe split into when it reaches the lungs?
    The wind pipe splits into two Bronchi. One Bronchus to each lung.
  4. What are the smaller tubes the bronchi split off into called?
    The Bronchi split into small tubes called Bronchioles.
  5. What are the structures at the ends of bronchioles called?
    The Bronchioles lead to the alveoli (air sacs)
  6. What are the lungs adapted to do for gas exchange?
    Lungs are adapted to speed up gas exchange.
  7. What adaptation does the alveoli give to help gas exchange?
    The many Alveoli give the lungs a huge internal surface area.
  8. How does a large surface area help gas exchange?
    Alveoli's large surface area allows more particles to travel at the same time.
  9. What surrounds the alveoli?
    There is a good blood supply surrounding the alveoli.
  10. Why does a good blood supply improve the rate of gas exchange?
    Alveoli's good blood supply maintains the difference in concentration.
  11. How thick are the alveoli?
    Alveoli walls are only one cell thick.
  12. Why does the thin alveoli wall help gas exchange?
    Alveoli's one cell thick walls reduces the distance the particles have to travel between the air and the blood.

Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
