The part of the digestive system that absorbs water and electrolytes and compacts indigestible matter into feces?

• A. Small Intestine
• B. Large Intestine
• C. Esophagus
• D. Stomach

Answer: (B)

The large intestine is where water and electrolytes are absorbed and indigestible material is compacted into feces. After most nutrients have been absorbed in the small intestine, the colon reclaimes remaining water and electrolytes, drying the material and forming solid waste. It also hosts gut bacteria that aid in breaking down leftovers and synthesizing some vitamins, with the resulting feces stored until defecation. The other parts have different main roles: the small intestine focuses on nutrient absorption, the stomach on digestion and mixing, and the esophagus on moving food to the stomach.
