To increase the surface area of the tubule.
It creates a larger surface area for re-absorption to occur, and thus more diffusion can occur at once.
Plicae circularis.
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
micro villi in the jujeum (second part of your small intestine)
They are called villi.Also there are micro villi on villi.
A microvillus is a small, finger-like projection on the surface of a cell that increases the cell's surface area for absorption of nutrients and molecules. They are commonly found in cells that specialize in absorption, such as in the intestines or kidneys.
A micro villi is a micro villi
The tiny fingerlike projections that cover the folds of the small intestine are called villi. Villi increase the surface area of the small intestine, allowing for more efficient absorption of nutrients from digested food.
The finger-like structures in the small intestine, called villi, increase the surface area for absorption of nutrients. This allows for more efficient absorption of nutrients from digested food into the bloodstream.

Plicae circularis.
the villi vastly increases the surface area for the absoption of food.
The villi is only one cell thick so it easier to absorb.
Villi (singular villus) are finger-like structures that are found on the inner wall of small intestines. Villi function to absorb glucose, amino acids and water soluble vitamins by diffusion into the blood capillaries in the villi.
The small intestine- micro-villi specifically in the small intestine. The micro-villi increases the surface area of the small intestine. which allows more food particles to enter the cells of the small intestine to digest.
In the intestinal wall, the villi (with micro-villi on them) are used to increase the surface area (just like the inside of your lungs do). This means that in the relatively small space, a lot of the nutrients in the food you eat can be absorbed by them and then diffused into the blood stream.
