title: [Oxygen diffusion through the walls of arterial vessels].
abstract: A newly developed mathematical model aided to study the regularities of the oxygen tension distribution in the wall of arterial vessels and in surrounding tissues at different physiological and morphological parameters determining the O2 transport in tissues. The model consists of a system of the second order differential equations. The maximal level of the oxygen tension in outer wall of the vessels was observed in arteriolar vessels of 80-160 mu diameter. The model computations suggest that the arteriolar vessels with the wall thickness over 120 mu, for normal functioning of their outer wall's cells, must obtain oxygen not only from their own blood but from an additional source, too.
