SEM Panoramic Views of Chaotic Bifurcated Bronchioles and Aggregated Alveolar Patterns of the Lung

抄録

In this study scanning electron microscopic (SEM) views of chaotic patterns of bifurcated bronchioles and aggregated alveoli of the corrosion cast of the human lung were revealed. The number of the respiratory bronchioles was about the 23 xth power of 2, and the number of the alveoli perbadult lung was estimated about 300 million qat the end of the bronchioles. The respieratory bronchioles revealed about 30 aggregated alveoli. These SEM bronchiole patterns with variously shaped aggregated alveoli looked like the bifurcation diagram which may lead to a chaotic attractor.
