AB The  majority  of  diseases  of  the  respiratory  system  present  with  cough  and/or  dyspnea  and  fall  into  one  of  three  major  categories:  (1)  obstructive  lung  diseases;  (2)  restrictive  disorders;  and  (3)  abnormalities  of  the  vasculature.  Obstructive  lung  diseases  are  most  common  and  primarily  disorders  of  the  airways,  such  as  asthma,  chronic  obstructive  pulmonary  disease  (COPD),  bronchiectasis,  and  bronchiolitis.  Diseases  resulting  in  restrictive  pathophysiology  include  parenchymal  lung  diseases,  abnormalities  of  the  chest  wall  and  pleura,  and  neuromuscular  disease.  Pulmonary  embolism,  pulmonary  hypertension,  and  pulmonary  venoocclusive  disease  are  all  disorders  of  the  pulmonary  vasculature.  Although  many  specific  diseases  fall  into  these  major  categories,  both  infective  and  neoplastic  processes  can  affect  the  respiratory  system  and  result  in  myriad  pathologic  findings,  including  those  listed  in  the  three  categories  above  (Table  278-1).
