Flow of air from external nares to alveoli

WebFor pulmonary respiration, air enters through the external nares into the olfactory chamber and into the internal nares. It goes into the buccopharyngeal cavity, through an open glottis, and into the laryngo-tracheal chamber. Then, it travels through the bronchi to reach the alveoli in the lungs. WebFeb 17, 2012 · The bronchi lets out air into the alveoli Inside the alveoli carbon dioxide is traded for oxygen through diffusion. Next air leaves though your mouth or nose.
