The large intestine is the very last section of the intestines and the digestive system. By the time the food gets here, its digestion is already complete. The wall of the colon has villi, in which active absorption of the liquid part takes place. Therefore, dense feces are formed here.

These same bacteria are capable of producing some vitamins, therefore they are essential.
