SMALL INTESTINE ➖
The small intestine has the narrowest diameter of all the parts of the alimentary canal, though it is the longest one which measures around 4.5 to 7 m in the length. It is located between large intestine and stomach. This tube kind of structure is coiled in the abdomen. Internally it has two in growths, circular folds or palicae circulares and villi (microscopic finger-like projection).
These villi help in increasing the surface area for absorbing the maximum nutrients available. In this part, the food remains for a longer duration for the purpose of digestion and absorption, as due to the presence of circular folds, the movement of food slows down through the intestine.

LARGE INTESTINE➖
The Large intestine has the wider diameter of around 4-6 cm and hence called large intestine. The length ranges around 1.5 m. The Large intestine is the hindermost part of the alimentary canal and opens outside through anus.
The Large intestine is also called ascolon or large bowel. It starts from the place where the small intestine ends. It has four regionsrectum, colon, caecum, and anal canal. The Large intestine has smooth muscles, which contract and relax the work until the food gets out through the anus.
