<human>: How does the body digest food?
<bot>: The digestive system is responsible for breaking down and absorbing nutrients from food. It begins with chewing, which helps to break up food into smaller pieces. Then, saliva in the mouth starts to break down the food further, while enzymes in the stomach start to break it down even further. In the small intestine, water is added to the mixture, allowing it to move along more easily. Finally, in the large intestine, the waste products are removed from the body through defecation.
