Two models explaining the etiology of parenchymal airspace enlargement in COPD. Panel A. Alveolar inflammation leads to destruction of alveolar walls and the elastic connective tissue fibers that link the acinus to the terminal airways. This allows the terminal bronchioles to recoil and obstruct. Panel B. Inflammation in the terminal bronchioles causes wall thickening, obstruction, and ultimate severing or stretching of the elastic connective tissue fibers. This loss of support for the distal acinus leads to folding (and ultimate destruction) of unsupported alveolar walls and enlargement of the duct.
