The microvilli have finger-like shapes originating from the villi that line the small intestine. They greatly increase the surface area of individual cells when it comes to absorbing nutrients.

microvilli increase surface area for absorption
They are located in the small intestine and help with absorption of nutrients from digested food. They also increase a cells surface area
Absorption of materials
Microvilli, villi, plicae circulares, if choosing just one i would go with microvilli because the tremendously increase the surface area for absorption in the absorptive cell
The intestinal wall has invaginations (or dips) that have a much larger surface ares compared to a simple tube

If the villi of the intestines had no microvilli, the absorption rate of the intestines would be significantly reduced. Microvilli are tiny finger-like projections on the surface of the villi that increase the surface area for absorption. Without microvilli, there would be less surface area available for nutrients to be absorbed into the bloodstream, leading to a decrease in absorption efficiency.

Microvilli cells are simple columnar epithelium. Stratified epithelia don't have cilia or microvilli because they are on the inner layers of epithelia. Think about it, cillia and microvilli are used to help the processes of absorption and secretion within the lumen. ex: upper respiratory tract.
