Question

Why Is Small Intestine Longer Than The Large Intestine

Answer 1

The duodenum begins to absorb nutrients from the food passing through its lumen. ... Any last nutrients that were not absorbed in the jejunum are absorbed in the ileum before the food passes into the large intestine. The large intestine is about 2 ½ inches in diameter and about 5 feet long in a living body.

Answer 2

Herbivores eating grass need a longer small intestine to allow the cellulose to be digested. Whereas Meat is easier to digest, hence carnivores like tiger have shorter small intestine.
