The stomach is like a sac and is approximately eight inches long. It mixes the bolus with acids to create a mixture called chyme. The stomach is protected from the acids by a special lining. The thick muscles surrounding the stomach, help break down the chyme into smaller peices. The stomach lining produces many digestive juices called gastric acids, which contain many enzymes that disolve nutrients. The chyme leaves the stomach bit by bit and is sent to the pancreas, and then to the small intestine. |
