 9/14/11 1. Oral Cavity:  Where the digestive system begins by the process of food being  masticated. 2. The food travels down through these two pipes. 3. Stomach:  The food reaches the stomach and is then broken down by natural  chemicals that are in the human body. The chemicals are called hydrochloric acid,  pepsinogen and gastrin. Each of the three chemicals help digest and break down the  food. 4. Duodenum:  The next step the food will be digested by. This part of the digestive  system takes place in the small intestine and goes through a process which a bile  helps break down the fatty food substances. 5. Jejunum:  Is a part of the small intestines, and this step uses a process call lactase  which breaks down sugars. 6. Ileum:  This section of the small intestine takes the nutrients and water into the body. 7. Large Intestine:  This is the last step in the digestive system, the food will now  become fecal matter that will eventually be pushed through the rectum and out the  Digestion
