Abstract:
In hypoxia, the tissue counter-current can thus, by virtue of the Bohr effect, increase tissue Po2 and thus tissue oxygenation. In hyperoxia, on the other hand, the counter-current system, acting as a diffusion shunt, can protect the tissue against adverse O2-toxic effects. It thus appears, that the counter-current system is advantageous for O2 supply to tissues.
