Topological properties of typical human organs, such as the circulatory system, the liver tissue and the lung airway, are explained. Next, a computer simulation of constructing a lung airway is introduced, which has been made by the group of this author. An algorithm of this simulation is based on the function of the lung and some anatomical data. The former is to distribute air equally to all parts of the lung with minimum energy consumption. Nine rules are assumed as an algorithm to generate successive branching within a given outer boundary from a given initial condition (main trunk, trachea). The resulting airway system is quite similar to the real one. As an application of this result, a new method of diagnosis of lung cancer and inflammation is proposed. As another application of the present method airway systems within a sphere and a cube are constructed. A hope for future development of a new field "computational anatomy" is expressed.
