the progressive narrowing and hardening of the arteries over time
QuestionAnswer
surgical creation of an opening through the thoracic wall to enter a pleural cavity
entry of air into the pleural cavity resulting from penetrating wound to parietal pleura
this pleura covers the lungs and is adherent to all its surfaces
