Inner folds are called villi and they increase the surface area and increase the efficiency of digestion and absorption by increasing the contact of intestinal secretions and food particles and also food particles and the inner surface lining of intestine.

∙ 14y agoThe villi massively increases the surface area upon which absorption can take place. The villi themselves are not fold but the inner surface of the folds in the small intestine. The lining of the s. intestine is covered by hundreds of tiny folds the bases of which are called crypts and the peaks of which are where the villi can be found.
These villi are also covered with thousands of microvilli which serve to increase further the amount of surface area available for absorption.
Hope that helps

What might be the advantage of the folds and coils of the small intestines?
slows down the passage of the food slomg the intestines, and afford an increased surface for absorption. Increase the surface area for the intestines to increase absorption of nutrients
