Best Answer

The villi vastly increase the effective surface area of the small intestine, allowing nutrients to be rapidly absorbed. Without them, the process would take longer, perhaps prohibitively longer. If the reduction in surface meant slower motion of the food, it might become necessary to eat more frequently to provide the same nutrients, and this would also mean more food bulk within the intestines at any given time.

This can already be observed in individuals who have lost part of their digestive systems to injury or disease, and have to adjust their type of food intake (predigested) or limit their activities because insufficient calories are absorbed in the jejunum.

If he lining if the small intestine were completely smooth then the intestine would have less surface area than it would normally have if it was lined with villi.

If you didn't have villi that would cause a person to get underweight because alot of the food molecules would not get absorbed. The rest of the food molecules would be excreted.

The would be less surface area with which to absorb digested nutrients.

The nutrients in the chyme would not be absorbed by the villi and your body would not get the nutrients.


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.


What would a villi job be?

a villi is a finger-like organ normally found in the intestine which have ripples. the ripples on the villi that held the nutrition from the foods we eat and disaperse them troughout the body a little at a time.

Does villi get rid of wastes in the body?

No, villi are for absorbing nutrients in the small intestines- they uptake minerals & vitamins, proteins and carbohydrates that the body needs. Waste is removed by defaecating and urinating.


Where in the body is food absorbed through the villi?

Yes, absorption in the small intestine occurs through the villi.
