摘要：

The calculations of resistance of oxygen access to the surface of alveolar sacs in human respiratory system were performed. The airways morphology was described by Weibel's model. The changes of alveolar sac diameter during breathing cycle and the unsteady flow conditions were taken into account. The resistance of oxygen transport for healthy case was compared with several pathological cases, namely insufficiency of breathing, emphysema, congestion-thrombotic diseases and interstitial diseases. Results of calculations show, that in each pathological case, the resistance of oxygen transport in human alveolar sacs is higher than for healthy one.
