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.

Does the villi absorb fat?
Yes, the villi in the small intestine help absorb nutrients, including fats. Fats are broken down into smaller molecules called fatty acids and glycerol, which are then absorbed through the villi into the bloodstream to be used as energy or stored by the body.
How does the internal surface of the colon compare with the internal surface of the small intestine?
The internal surface of the colon is relatively flat with numerous outgrowths called haustra and lacks villi. In contrast, the internal surface of the small intestine is highly folded and covered with finger-like projections called villi, which increase the surface area for nutrient absorption.
What are the three types of villi?
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
Are finger like projections of the mucosa?
Villi. Most absorbtion occurs in the ileum btw.
What is the small finger-like bumps in the small intestine?
They are called villi.
Finger-like structures that cover the inner wall of the small intestine?
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.
