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.
摘要
在缺氧状态下，组织逆流可借助波尔效应提高组织的氧分压，进而增加组织的氧合作用。另一方面，在高氧状态下，逆流系统作为一种扩散分流器，可保护组织免受有害的氧中毒效应影响。因此，逆流系统似乎有利于向组织供应氧气。
