AB The  principal  physiologic  role  of  the  lungs  is  to  make  oxygen  available  to  tissues  for  metabolism  and  to  remove  the  main  byproduct  of  that  metabolism,  carbon  dioxide.  The  lungs  perform  this  function  by  moving  inspired  air  into  close  proximity  to  the  pulmonary  capillary  bed  to  enable  gas  exchange  by  simple  diffusion.  This  is  accomplished  at  a  minimal  workload,  is  regulated  efficiently  over  a  wide  range  of  metabolic  demand,  and  takes  place  with  close  matching  of  ventilation  to  lung  perfusion.  The  extensive  surface  area  of  the  respiratory  system  must  also  be  protected  from  a  broad  variety  of  infectious  or  noxious  environmental  insults.
