Ideas in Theoretical Biology - Comment About the Fractality of the Lung



It is generally believed, that when the surface/volume ratio is high, fractal structure is expected to exist. The branched fractal structure of the lung has been cited as a “classical” example of this statement. In this short paper I would like to demonstrate that an alternative “lung” structure (namely sponge-like fractal) is at least as good as, or even better than the branched one, concerning this ratio, therefore, the cause of the lung's fractality lies elsewhere.
