AB Alveolar  ventilation  is  defined  as  the  volume  of  fresh  air  entering  and  alveolar  air  leaving  the  alveoli  per  minute.  The  two  volumes  are  not  usually  exactly  equal  because  not  every  molecule  of  oxygen  used  by  the  body  results  in  a  molecule  of  CO2  released  by  the  body,  and  also  because  of  the  heating  and  humidification  of  inspired  air  described  in  Chapters  25  and  34.  Alveolar  ventilation  is  not  the  same  as  the  ventilation  per  minute  measured  at  the  nose  or  mouth  because  not  all  of  the  air  entering  the  body  per  breath  reaches  the  alveoli.  A  substantial  portion  of  each  inspired  breath  remains  in  the  conducting  airways  and  does  not  enter  the  alveoli.
