    • Scarring of the lung
    • air sacs of the lung become replaced by fibrotic tissue
      • when the scar forms, the tissue becomes thicker causing an irreversible loss of the tissue's ability to transfer oxygen into the bloodstream
    • gaseous exchange involves DIFFUSION, which relies on a thin alveoli lining
    • reduced elasticity of the lungs
      • exhaling relies partly on the elastic recoil of the lung tissue
        • if elasticity is reduced, breathing out becomes difficult
      • shortness of breath, especially when exercising
      • chronic dry cough
      • pain and discomfort in the chest
      • weakness and fatigue
