The respiratory system is crucially important to us, it allows to exchange gas. meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillary by diffusion.

Two things happen external and internal respiration. External, is the action of bringing in air literally.. by just breathing. Internal, is the cellular respiration that occurs simultaneously as we breathe.

The main function of the respiratory system is to take in oxygen, for all the cells of your body, and remove carbon dioxide.
To supply the blood with oxygen.
