===Meaning===
[[File:VilliPicture.png|right|300px|thumb|A computer generated image of many villi.]]
[[Villi]] are small folds in the wall of the [[Small Intestine|small intestine]] that increase its [[Surface Area|surface area]].

Singular [[Noun]]: '''Villus'''
Plural [[Noun]]: '''Villi'''

===Adaptations of Villi===
: [[Villi]] have a wall only one cell thick so the [nutrient]]s only have a short distance to [[Diffusion|diffuse]] into the [[blood]].
: [[Villi]] [[Capillary|capillaries]] inside them for a good blood supply to allow for quick [[diffusion]] into the [[blood]].
: [[Villi]] have a large [[Surface Area|surface area]] to allow quicker [[diffusion]].
: The [[Cell (Biology|cells]] in the walls of the [[villi]] have [[microvilli]] to provide an even bigger [[Surface Area|surface area]] for quicker [[diffusion]].

===About Villi===
: [[Villi]] cover inside of the [[Small Intestine|small intestine]].
: [[Villi]] increase the [[Surface Area|surface area]] of the [[Small Intestine|small intestine]].
