Fingerlike projection known as villus. The villi increase the surface are another 10FOLD.
They are located in the folds of the small intstine and absorb nutrients from DIGESTED foods
In order to get the nutritional benefit from the foods you eat, the food must first be broken down into its most basic nutrient elements. These tiny nutrients are then absorbed out of the digestive tract and into your bloodstream. Your small intestine is the section of your digestive tract where the majority of nutrient absorption takes place. In this lesson, you will learn about the unique modifications within the wall of the small intestine that allow for maximum absorption.

Thin submucosa for rapid enzyme release and nutrient absorption.
Highly vascular for rapid nutrient absorption.
Huge surface area on account of microvilli.
Very long, to increase the time food is present for nutrient absorption.
