<s>[INST] What is the process of digestion in human body [/INST] The process of digestion in the human body involves the breaking down of food into smaller molecules that can be absorbed and used by the body for energy and nutrition. The process starts in the mouth with chewing and the release of saliva, which contains an enzyme called amylase that starts breaking down carbohydrates. The chewed food then travels down the esophagus and into the stomach, where it is mixed with stomach acid and digestive enzymes to break down proteins. The partially digested food then moves into the small intestine, where it is mixed with bile from the liver and digestive enzymes from the pancreas, which help to further break down the food and absorb the nutrients. The remaining waste is then moved into the large intestine, where water and electrolytes are absorbed and the remaining waste is eliminated through the rectum and anus.</s>\ <s>[INST] What is the purpose of digestion?
