The small intestine has small tiny projections called "villi". These projections increase the surface area for absorption. The large intestine however lacks these structures.
The small intestine is about 5 meters long; this provides a large surface area for the absorption of nutrients
finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
To allow a greater surface area for nutrient absorption.
The major site of nutrient absorption is the small intestine.
Villi
Villi
Microvilli for increase surface area for absorption
Villi, to increase the surface area for absorption.
The absorption for any nutrient occurs in the small intestine
The wrinkles of the small intestine increase its surface area. Increased surface area gives more opportunities for absorption of nutrients, which is one of the main functions of the small intestine.
