The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe. The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air.
