This powerpoint presentation covers Topic 6.4 in the IB Biology curriculum. Specifically, it covers the basics of the respiratory system including the mechanics of ventilation and gas exchange.


Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
