A theoretical model of gas transport between arterioles and tissue.

摘要: Abstract A theoretical model of CO 2 and O diffusion between arterioles tissue was developed to determine if significant transport could occur in precapillary vessels. There is increasing evidence, both experimental, that such exchange does occur. Using a which were coupled through the Bohr Haldane effects, we quantified radial axial transport. We also examined roles arteriole wall capillary structure on Capillary arrangements investigated included capillaries independent with entering P or equal constant, branching off along length partial pressure at given location. found for an inner diameter ranging from 200 22 μm, exiting blood 6 45% way complete equilibrium surrounding tissue, respectively.
