Abstract

In the normal process of digestion, not only substances in solution are absorbed. Solid, undissolved particles in macrocorpuscular form, are "kneaded" into the mucosa during their passage through the digestive tract. These particles in the micrometer size range pass between the epithelial cells into the subepithelial layer. From here they are transmitted both by the lymph vessels and by the mesenteric veins into the circulation, where they remain for a considerable time. This phenomenon, termed persorption, was investigated in detail.

摘要

在正常消化过程中，不仅溶液中的物质会被吸收。呈大微粒形式的固体、未溶解颗粒在通过消化道时会被“揉进”黏膜。这些微米尺寸范围内的颗粒在进入上皮细胞之间后进入上皮下层。它们从这里通过淋巴管和肠系膜静脉进入循环系统，并在其中停留相当长的时间。这种被称为渗透吸收的现象已得到详细研究。
