Two differently oriented approaches in intestinal physiology can be distinguished. One, mainly based on in vitro experiments, seeks explanations at the level of the epithelium itself. The other, mainly based on in vivo experiments, looks for explanations at the level of regulatory nervous and endocrine mechanisms and their interaction. These two approaches complement each other.
在肠道生理学中，可以区分出两种不同的研究方法。一种主要基于体外实验，试图在上皮细胞自身层面寻找解释。另一种主要基于体内实验，着眼于调节性神经和内分泌机制及其相互作用层面来寻找解释。这两种方法相互补充。
