Digestion is the journey of food and ingested substances from the mouth until the end of their journey when some of it might be excreted. The digestive system is made up of the mouth, oesophagus, stomach, small intestine, large intestines and the pancreas. the process of digestion involves many different enzymes. Digestion starts in the mouth where salivary amylase breaks down starch into maltose. Stomach acids break down the food further before it moves on to the epithelial membrane of the small intestine where maltase breaks down maltose into glucose which can then be absorbed. There are several enzymes each specialised to break down a specific molecule in our diet ( e.g proteases for proteins).
