The digestive system changes the food we eat into usable and unusable materials. Where do unusable materials go until disposal?

The process in which the complex and insoluble contents of food are converted into simpler and soluble substances, suitable for absorption and assimilation is called digestion. The food is digested by the digestive system with the help of digestive enzymes. The usable materials are absorbed by the small intestine and the unusable food is passed on to the large intestine where the water is absorbed and moves to the anus for removal. Hence, the digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food and unusable material goes into the large intestine to await disposal.
So, the correct option is 'Large intestine to await disposal'.
