Abstract
The movement of sodium and potassium has been studied in terminal ileum and proximal jejunum of anaesthetized rabbits. The absorption of sodium in terminal ileum increases witht the intraluminal concentration, absorbing this cation against concentration gradients, from levels as low as 55 mEq/ l. The movement of sodium is related to that of chloride, in such a way that there appears to exlst a dependence between the transportation of both ions. The situation in the jejunum is comparatively similar, although the absorption of sodium is generally greater in the ileum than in the jejunum. It appears that the movementt of potassium in both parts of the intestine studied occurs through a simple passive process.
