No, the length increases. When you are alive, the muscles are contracted in folds, and when you die, these folds relax, expanding the small intestine.
The organ in the abdominal cavity that has folds similar to those in the stomach wall is the small intestine. The inner lining of the small intestine features folds called plicae circulares, which increase the surface area for absorption, much like the rugae in the stomach that allow for expansion and enhance gastric function. Both structures serve to optimize their respective organ functions through increased surface area.
permanent folds are called plicae circulares temporary folds are called rugae.
The villi are the tiny finger-like projections that cover the folds of the small intestine. The singular of villi is villus.
