250. The digestive system begins in the mouth where food is broken down mechanically and chemically. The food passes through the pharynx and is moved down the esophagus to the stomach. Acid and movement break the food down further. Chemicals are produced and then released in the liver, gall bladder, and pancreas to the small intestine. Food is broken up further in the intestine and nutrients are absorbed. Water is absorbed in the large intestine and vitamins made. The waste is collects in the rectum until disposal.
