The role of the large intestine in human digestion is primarily to absorb water and electrolytes from indigestible food matter, facilitating the formation of feces. After nutrients have been absorbed in the small intestine, any remaining material is passed to the large intestine for further processing. The large intestine also houses a complex community of bacteria, which aid in the fermentation of undigested carbohydrates and contribute to gut health. Maintaining the health of the large intestine is crucial for overall digestive health.
