The villi in the small intestine are small finger like projections, which increase surface area for the absorption of nutrients. They is richly supplied with blood vessels, which get nutrients from here and transport them to the rest of the body.

The function of the villi and microvilli of the small intestine is to increase the surface area in order to maximize the efficiency of absorption. - tyler (I'M EXTREMELY VAIN AND FULL OF MYSELF) soon to be greatest guitarest

The villi and circular folds of the small intestine increase the surface area available for absorption of nutrients. Through absorption, nutrients enter the circulatory system, which carries nutrients to all body cells.

Villi increase the surface area of your intestines, thereby increasing the surface area through which nutrients can be absorbed from the matter being digested.

These very small finger like projection form a very large surface area. These can now fit into a smaller space.

What is the function of an epithelium that is smooth on its free surface compared to an epithelium with a folded free surface made up of micro-villi?

Secretion is one of epithelium's major functions. However, if there are microvilli, they are used for absorption. Regular epithelium would be in our skin, and epithelium with microvilli would be in the digestive tract.

What are the major roles of the villi and microvilli in the small intestine?

Villi are responsible for absorbing nutrients from the small intestine into the bloodstream, for transport to the liver and other cells. In order to increase the amount of nutrients taken into the bloodstream, each villus itself has dozens of microvilli, to increase greatly the surface area.

What relationship exists between villi and microvilli?

Yes. A villi is a fingerlike structure in a small intestine that absorbes the nutrition from the food you ate. A microvilli is basically a villi on a villi which is what actually does the absorbing


Why do microvilli differ in appearance?

Inside microvilli you have actin, and inside cilia you have microtubules. Cilia are larger than microvilli, and cilia can be seen in the upper GI tract to beat away mucous which traps bacteria, virus, and other particles, microvilli is often seen in the intestines of the GI tract for nutrient absorption.Hope that helps!


What would happen to your body's absorption rate of the intestines if villi had no microvilli?

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.
