The "villi" of the intestines increase the surface area dramatically. Each villus is basically a loop of the intestine wall. The polyps that are often found in the large intestine exhibit similar structure.
Plicae and villi
The stomach lining is quite smooth. The small intestine is lined with villi which increases surface area. Think of villi as little round popsicle sticks protruding from the lining.
The surface is made up of many small wrinkled folds which increases the surface area.

the villi vastly increases the surface area for the absoption of food.
You can't absorb that which doesn't make contact with the surface.
the villi in 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
The villi increases the surface area for the small intestine.
The folding of the mucosal membrane increases the surface area of your small intestine, thus allowing more nutrients to be absorbed.
Simply put, larger surface area allows for more digestive process to occur.
The finger-like projections in the small intestines are called villi & they are present in the small intestine to increase the surface area of the intestinal wall. A greater surface area allows the intestines to absorb more nutrients from the digested food into the blood stream. Villi are prominent in the small intestines because this is where majority of the absorption of nutrients occur. Villi also play a small role in the digestion of food.
