Presentation transcript:

Modeling the Relationship of the Pleura and Lung Deflate a rubber or plastic sphere so that it assumes a hemisphere with a concave and convex surface. Place a model lung in the concavity and cement the lung surface to the inner surface of the hemisphere. On the right, in cross section, the parietal pleura is represented by the convex surface of the hemisphere; the cemented layers represent the visceral pleura. To complete the model, exhaust the hemisphere of air, replacing it with a little fluid to lubricate the inner surface. This geometry should be visualized in the examination of the chest and when looking at X-ray films, remembering that the pleural surfaces are anterior, lateral, medial, and inferior.
