Answer:

It brings O2 from the air to a gas exchange surface in an organism.

Respiratory organs can be used for this purpose

Explanation:

Pulmonary ventilation, or breathing, exchanges gases between the outside air and the alveoli of the lungs. The ventilation is also carried out by the respiratory system. It is used to breathe in oxygen for natural processes and then expel gaseous wastes, such as moisture, carbon dioxide and trace amounts of other gases. This system gives oxygen directly to the blood; the blood distributes the oxygen everywhere else.
