The respiratory system is made up of the nasopharynx, the larynx, the trachea, the bronchi, and the lungs.
Aspiration: the lungs contract (shrink) and release carbon dioxide through the bronchial tubes and trachea, which goes out through the nose and mouth.
Inspiration: air enters through the nose and mouth; through the larynx, trachea and bronchi it reaches the lungs. The lungs dilate (increase in size). At this point oxygen from the air passes into the blood and the blood in turn gives up the carbon dioxide that needs to be removed from the lungs.
