FunctionThe purpose of the gastric rugae is to allow for expansion of the stomach after the consumption of foods and liquids. LocationRugae can appear in the following locations in humans:
Difference between rugae and intestinal villiRugae are only evident when an organ or tissue is deflated or relaxed. For example, rugae are evident within the stomach when it is deflated. However, when the stomach distends, the rugae unfold to allow for the increase in volume. On the other hand, plicae remain folded regardless of distension as is evident within the plicae of the small intestine walls.
