Folds increase the surface area to volume ratio.
Imagine a circle with folds all around the edge and another circle the same size with a flat edge. Both circles have the same volume, but the one with the folds has a much larger surface area.
First of all, this is not an opinion question. It is purely factual. Most digestion takes place in the small intestine because that is where nutrients are absorbed and some of the food is broken down by chemicals (although some of that happens in the stomach, as well). The large intestine only absorbs water.
The digestion first starts in the mouth and the food is absorbed in the small intestine, and the water and minerals go to your large intestine:)learned this in biology, last week =)
both rugae and villi are specialized "folds". the rugae allow your stomach to expand when you eat (like a balloon) and the villi increase the surface area in your small intestine for nutrient absorption
Most of the absorption of nutrients occurs in the small intestine. The inner surface of the small intestine is lined with finger-like projections called villi, which increase the surface area available for absorption. This is where the majority of nutrients from food are absorbed into the bloodstream.
absorption of nutrients by increasing the surface area available for absorption. This increased surface area allows for more efficient absorption of nutrients from the digested food passing through the small intestine.
The primary organ of digestion and absorption of nutrients is the small intestine, especially the duodenum.In general, you could say the stomach breaks down the food, the small intestine digests and absorbs the food, and the large intestine absorbs water.

The small intestine is a long convoluted tube where the majority of chemical digestion and nutrient absorption takes place in the body. It is lined with villi and microvilli that increase the surface area available for absorption of digested nutrients into the bloodstream. Various enzymes and bile from the pancreas and liver play crucial roles in breaking down food molecules in the small intestine.

Villi increase the rapid absorption of food away from the small intestine.
It is the Duodenum!Actually, most chemical digestion, in humans, takes place in the small intestine.Chemical digestion takes place in the small intestine, the stomach and the mouth.
The finger-like structures covering the inner lining of the small intestine are called villi. Villi are specialized structures that increase the surface area of the small intestine, allowing for better absorption of nutrients from digested food into the bloodstream. These structures play a crucial role in the process of digestion and nutrient absorption.
Villi are finger-like projections in the small intestine that increase its surface area for nutrient absorption. Bile is a digestive fluid produced by the liver and stored in the gallbladder, which helps in the breakdown of fats in the small intestine. Villi aid in nutrient absorption, while bile aids in fat digestion.
The small intestine has small tiny projections called "villi". These projections increase the surface area for absorption. The large intestine however lacks these structures.
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
