It is known that in oxygen concentration proles for capillary beds of skeletal muscles, radial diusion most likely has considerably more eect on oxygen transport in long and parallel capillary beds than axial diusion. However, axial diusion may still play a signicant role in oxygen transport in tissue, especially in relatively short pathways. Our model adds to known solutions the component of axial diusion to multi-capillary beds inside a tissue cylinder, where arbitrary characteristics include random locations and uneven oxygen strengths. Discussion of the solutions for oxygen supply in multicapillary beds near the arterial ends, in the central regions, and near the venous ends in capillaries is introduced in the remainder of the article. To account for relatively small longitudinal diusivities, we use perturbation methods to solve the associated governing equations.
