<human>:  Can you explain the function of the digestive system?
<bot>: The digestive system is the system responsible for the breakdown of food so that its nutrients can be used by the body. It begins with the mouth, where food enters and is broken down by chewing and saliva. After that, the food travels down the esophagus to the stomach where acids will break it down further. From the stomach, the food travels to the small intestine where digestion occurs. Nutrients are absorbed into the bloodstream and travel throughout the body. Finally, the waste travels to the large intestine, where water is removed, and the waste is then eliminated from the body through the rectum.
