The document/notes is a basic summery of gas change process of the respiratory systems. It’s an ATAR notes with basic informations, and later on you can build more information or in depth information on the topic, with the help of these basic information.

For gas exchange to occur
there needs to be a

Differentin concentration between air The concentration ofoxygen is higher
in alreaus compared to bloodin in the alveolus compared to the capillaries,
capillary. Therefore oxygen diffuse from alveolus
