Detailed explanation-1: -The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

Detailed explanation-2: -The correct timing of material through the large intestine is critical for the formation of healthy stool. If material is pushed through too quickly, not enough water is absorbed and the stool is left with a high water content, which results in diarrhea.

Detailed explanation-3: -The large intestine absorbs water, salts, and some vitamins. Most nutrients are absorbed in small intestine.

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.
