Detailed explanation-1: -By the time indigestible materials have reached the colon, most nutrients and up to 90% of the water has been absorbed by the small intestine. The role of the ascending colon is to absorb the remaining water and other key nutrients from the indigestible material, solidifying it to form stool.

Detailed explanation-2: -Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.

Detailed explanation-3: -The large intestine functions to absorb any excess water from the material it receives from the small intestine. This also involves the collection of electrolytes, which move with water. Thus, the large intestine works to preserve and absorb water and electrolytes that were not absorbed by previous digestive organs.

Detailed explanation-4: -The large intestine is the portion of the digestive system most responsible for absorption of water from the indigestible residue of food. The ileocecal valve of the ileum (small intestine) passes material into the large intestine at the cecum.
