(Received 1 March 2005; published 12 October 2005)
We study the distribution nD of airway diameters D as a function of generation N in asymmetric
airway trees of mammalian lungs. We find that the airway bifurcations are self-similar in four species
studied. Specifically, the ratios of diameters of the major and minor daughters to their parent are constants
