The process of digestion is less than 100% efficient. This is for two reasons. First, not everything that we eat is digestible - particularly cellulose fiber, which is present in fruit and vegetables, beans, and other plant matter that we may be eating. Secondly, the human digestive tract (or alimentary canal) contains symbiotic bacteria, which help us to digest our food but which are not themselves digestible.
On extraction of whatever is useful to the human body, the balance material has to be ejected. This is done by the process of excretion. This enables the alimentary canal to remain clean and make way for fresh food.
