Presentation Transcript


  1. Lungs By the end of the lesson you should be able to: Label the internal structures of the lungs State the features of the alveoli which allow efficient gas exchange Explain the role of diffusion in gas exchange State the features of the capillary network that allow efficient gas exchange

  2. Breathing footprints breathing

  3. The lungs organs that allow gas exchange oxygen in / CO2 out trachea - has rings of cartilage bronchi (bronchus) bronchioles alveoli (alveolus) computer animation

  4. Alveoli (air sacs) provide large surface area for gas exchange one lung equivalent to a tennis court of surface area using alveoli footprints alveoli

  5. oxygenated blood air in air out air sac in lungs body cells deoxygenated blood skool gas exchange

  6. Features of Alveoli for efficient gas exchange large surface area to absorb oxygen. moist surface to allow oxygen to dissolve. thin lining to allow easy diffusion of gases. dense network of blood capillaries for easy gas exchange. skool adaptation of alveoli

  7. Features of capillaries for efficient gas exchange dense network to carry CO2 and O2 Large surface area to transport gases Lining is one cell thick so gases can pass through quickly and easily.

  8. Lungs Can you? Label the internal structures of the lungs State the features of the alveoli which allow efficient gas exchange Explain the role of diffusion in gas exchange State the features of the capillary network that allow efficient gas exchange
