The stomach (which is in the abdominal area) is lined with thirty-five million glands that produce about three quarts (2.85 liters) of gastric juices daily. Hydrochloric acid makes up roughly five percent of these juices and, together with other acids and various enzymes, constantly works to digest food particles.
