肝细胞的小管胆汁中水的运转被公认为渗透过程,即水及无机离子,按照肝细胞将溶质逐出而形成的渗透梯度,进入胆小管腔。但目前对此全过程了解还很少,也有不少争论,本文主要指出这些有争论的需进一步加以研究的问题。结构-功能关系肝细胞将胆汁分泌入胆小管是与肝细胞浆膜的高度极性化有关。胆小管是由两个邻近肝细胞侧浆膜的沟形成。以下讨论有关肝细胞浆膜的问题。 (一)肝细胞浆膜是高度极性化的
The operation of water in the bile of hepatocytes is known as the infiltration process, ie water and inorganic ions, which enter the bile duct lumen in accordance with the osmotic gradient formed by the excretion of solutes by the hepatocytes. However, little is known about this whole process at present, and there are many controversies. This article mainly points out those controversial issues that need to be further studied. Structure-function relationship The secretion of bile into hepatocytes by the hepatocytes is associated with a high degree of polarization of the plasma membrane of hepatocytes. The bile duct is formed by two adjacent serous serosal grooves. The following discussion of liver cell plasma membrane problems. (A) The hepatocyte plasma membrane is highly polar
