关于小肠吸收氧的问题,我们考虑,消化系统与呼吸系统在生物进化和胚胎发育上有密切关系。两系统都来自内胚层。脊椎动物的呼吸器官便是由消化道前半部分而来。同时基于细胞膜结构和氧的脂溶性质,也理应可以吸收。即氧与胃肠上皮细胞接触时,可以溶解入脂质膜中,并扩散到膜的另一侧。再脱离脂质膜进入对侧的水环境中。此外,从影响物质在细胞脂质膜上通透性的因素上看。几个因素均有利于氧的吸收。脂溶性质问题已如上述。物质
On the absorption of oxygen in the small intestine, we consider that the digestive and respiratory systems are closely related to the biological evolution and embryonic development. Both systems are from the endoderm. Vertebrate respiratory organs are from the first half of the digestive tract. At the same time, based on the liposoluble nature of the cell membrane structure and oxygen, it should also be able to absorb. That oxygen in contact with gastrointestinal epithelial cells, can dissolve into the lipid membrane, and spread to the other side of the membrane. Then from the lipid membrane into the contralateral water environment. In addition, from the factors that affect the permeability of the substance on the lipid membrane of the cell. Several factors are conducive to the absorption of oxygen. The problem of lipidolysis has been described above. substance
