The villi on the inner surface.
The minute structures that project from the inner walls of the small intestine are called villi. They help in the digestion process by continuously pushing digested particles in one direction. Their function is to absorb nutrients. These villi effectively increase the surface area of the intestine so more nutrients can be absorbed.
Millions of tiny hair-like protrusions, called villi, line the inside of the small intestine. They vastly increase the surface area of the intestines, to maximise diffusion of nutrients into the bloodstream. In fact, there are even smaller micro-villi covering the villi, to increase the absorption capacity even further! A constant supply of blood ensures a steep concentration gradient is maintained. This is a crucial factor for allowing as great an uptake of nutrients as possible.
It is refered to as the small intestine only because its diametre is small - about 1inch, but it is about 15 feet in length. It has a huge surface area on the inside, about the same as a tennis court, because its inner wall is corrogated and covered in fine, finger- like projections called villi, which in turn are covered in tiny hair-like projections called the microvilli.
Duramater or literally, tough mother. The brain has the dura, outer cover, and pos mater, little mother, as the inner layer. Ed, CNRN Retired.

Villi and microvilli
The digested food will go to the inner wall and it will carry to the bloodstream
These are called villi and there are millions of them that line the small intestine and large intestine (Colon) they absorb the nutrients particularly in the Colon where they absorb liquid into the blood stream. This is what makes your stools hard (constipation) and painful to pass if you wait too long to go for a number 2. The peristaltic action moves the liquid along the small and large intestines.
The inner wall of the small intestine is covered with millions of microscopic, finger-like projections called villi. These are responsible for distribution of food substance to all cells of the body.

They are called "plicae circulares"
The villi is found in the inner wall of the small intestine , it is covered with many finger like folds( Villi). The villi absorbs more digested food and is absorbed to the bloodstream.
A typhlosole is an internal fold of the intestine or intestine inner wall. Typhlosoles occur in bivalve mollusks and some annelids, and echinoderms.
