Digestion refers to the processes governing the breakdown of larger food molecules into simpler smaller forms with the help of digestive enzymes released by associated glands. Water and roughage help in easy passage of food down the gastrointestinal tract. Nutrients are the organic and inorganic constituents of food that need to be digested into our body. They play a major role in all the metabolic processes in our body.
