Villi
Villi
No, the largest organ in the digestive tract is small intestine but the largest intestine is called large intestine because its diameter is greater than small intestine while the widest part of digestive tract is stomach.
A cheetah (as with most other carnivores) has an enlarged stomach that represents more than half of its alimentary canal. This is because it is required to eat greater amounts of food compared to other animals.
The diameter of the large intestine is greater than that of the small intestine.
To allow a greater surface area for nutrient absorption.
Four features of the small intestine make it efficient at absorption of digested food: 1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!
The Greater Omentum

The Colon
The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
Colon is bin defined as the greater part of the large intestine
