to quickly digest food and absorb nutrients
The intestine aids in the digestion. It also absorbs and transfers nutrients and water into the bloodstream.
The digestive tube structure in both earthworms and grasshoppers consists of several folds. These folds affect the efficiency of food absorption by increasing the surface area.
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.
permanent folds are called plicae circulares temporary folds are called rugae.

circular folds
The villi are the tiny finger-like projections that cover the folds of the small intestine. The singular of villi is villus.
The circular folds or plicae circularis are the permanent folds or ridges of the mucosa.
They are called "plicae circulares"
folds and villi
The large intestine has folds and bumps, such as haustra and taeniae coli, to increase its surface area for better absorption of water and nutrients. These structures also help in the movement of feces through the intestine by promoting segmentation and peristalsis. Additionally, the folds and bumps enable the large intestine to expand and contract as needed to accommodate varying amounts of waste material.
