AB The  lung  receives  blood  flow  via  both  the  bronchial  circulation  and  the  pulmonary  circulation.  Bronchial  blood  flow  constitutes  a  very  small  portion  of  the  output  of  the  left  ventricle,  and  it  supplies  part  of  the  tracheobronchial  tree  with  systemic  arterial  blood.  Pulmonary  blood  flow  (PBF)  constitutes  the  entire  output  of  the  right  ventricle,  and  it  supplies  the  lung  with  the  mixed  venous  blood  draining  all  the  tissues  of  the  body.  It  is  this  blood  that  undergoes  gas  exchange  with  the  alveolar  air  in  the  pulmonary  capillaries.  Because  the  right  and  left  ventricles  are  arranged  in  series  in  normal  adults,  PBF  is  approximately  equal  to  100%  of  the  output  of  the  left  ventricle.
