Exploring the Anatomy of the Small Intestine: Circular Folds and Nutrient Absorption

The video tutorial explores the small intestine, highlighting its length and the presence of circular folds that increase surface area for nutrient absorption. It also explains how the spiral movement of Kime enhances contact time, further aiding absorption.

What role does the lining of the small intestine play in nutrient absorption?

Why is increasing contact time important for absorption in the small intestine?
