HUMAN NUTRITION

Detailed explanation-1: -The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

Detailed explanation-2: -The 4 major functions of the large intestine are recovery of water and electrolytes, formation and storage of faeces and fermentation of some of the indigestible food matter by bacteria. The ileocaecal valve controls the entry of material from the last part of the small intestine called the ileum.

Detailed explanation-3: -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.
