That is the villi (sing. villus.) The villi are built for absorption in the small intestine. They are small, finger-like projections on the inside of the small intestine. They increase the interior surface area of the small intestine 30-60x and aid digestion.
There are different kinds of villi:
- Villus Capillaries -- Take amino acids and sugars into the blood stream
- Villus Lacteal -- Collects absorbed chylomicrons, which are lipoproteins composed of triglycerides, cholesterol and amphipathic proteins, and are taken to the rest of the body through the Lymph fluid

What Increases the surface area of small intestines?
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.
Which structures of the small intestines increases the surface area available for absorption?
Plicae and villi
How does the structure of the small intestine help the intestine absorb nutrients?

How is surface area maximized in the stomach and small intestines?
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.
How does the structure of the small intestine help the Small intestine?
the villi in the small intestines.
What increases the surface área of the small intestine?
The surface is made up of many small wrinkled folds which increases the surface area.
Where in your bodies do you maximize surface area?
Nasal cavity tongue surface stomach epithelium length of both intestines kidney's coiled structure of the cochlea lung (alveoli) cerebral cortex capillaries microvilli in small intestines -many more... all i can think of right now
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
What structure prevents passage of materials from the small intestines to the large?
ileocecal valve
Why is large surface area important in our small intestines?
You can't absorb that which doesn't make contact with the surface.
What structure seen in the frog small intestines help abosrb food at this point?
Villi
