The villi are folds within the lumen of small intestine walls. The whole purpose of villi is to increase the amount of surface area to be able to absorb more nutrients. Without villi, food would pass too easily through the digestive system causing you to defecate (poop) more. And you wouldn't get as much nutrition our of the food that you do eat so you'd have to eat more as well.
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.
No, villi are not located in the esophagus. Villi are small, finger-like projections found in the small intestine that increase its surface area for nutrient absorption. The main function of the esophagus is to transport food from the mouth to the stomach.
-Villi The first answer is correct in the villi are very small finger like projections in the intestines but I would suspect the question refers to the appendix.
The finger like projections that line the small intestine are called, Villi.
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
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.
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.
