The small intestine is the largest in the digestive system because it has the largest surface area. The whole inside of the small intestine is covered in villi and micro villi and when spread out it would be about the size of 4 tennis courts! These villi and micro villi are there in order to allow the absorption of nutrients and gases into the circulatory system.

The huge surface area of the small intestine makes it , in terms of surface area, the largest organ in the digestive system. In terms of mass, the liver is the largest organ in the abdomen.

The average weight of the small intestines is about 400grams more than the liver and the surface area of the small intestines is larger than the liver. Therefore the small intestine is the largest most massive organ in the human body despite the claim the liver is the largest internal organ.

Small intestine is where the most of the digestion takes place. Also it is not the largest organ (liver is largest) but the longest organ (7 meters) in the digestive system.
