Increase surface area for food
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
The function of intestinal villi is to aid in the efficient and rapid absorption o nutrients.
Because Villi is a way for the small intestinal to increase it's surface. thus providing more space and more cells for absorption(main function). The colon on the other hand,it's primary function is to propel feces to the rectum (though is does absorb water and salts and some vitamins) and there's no need to increase it's surface because doing so doesn't help achieving it's function.
Villi are suited for their function because they greatly increase the surface area of the small intestine, allowing for efficient absorption of nutrients. Their structure includes a single layer of specialized cells called enterocytes that facilitate the absorption process. Additionally, villi have a rich blood supply and lymphatic vessels to transport absorbed nutrients quickly to the rest of the body.
No, cerebrospinal fluid is produced by the choroid plexus in the brain's ventricles. Arachnoid villi function to reabsorb and return cerebrospinal fluid back into the bloodstream.
the villi vastly increases the surface area for the absoption of food.
The villi is only one cell thick so it easier to absorb.
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
Finger like folds in the intestines called villi and microvilli aid in the nutrients being absorbed into the bloodstream. The function of the villi in the frog is it helps with the digestion process.
All villi increase surface area.
The function of intestinal villi is to aid in the efficient and rapid absorption o nutrients.
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.
it reabsorbs cerebrospinal fluid and returns it to the venous circulation

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.
To help food digest and help it to be absorbed more efficiently.
Capillary in the villi are used to absorb the digested food and transport the food the the destination cell.
