Human and Rabbit Digestive System
1. What part of the rabbit digestive system is much larger than the human’s? Why do you think that is?
2. Food travels through a tube called the alimentary canal . List all of the structures of this canal in the order that food travels through them.
3. Accessory organs assist in digestion, but food does not pass through them. Name three accessory organs shown in the diagram.
4. The image shows a human digestive system similar to the one of the previous page, except the large intestine is more accurate in that it shows the three sections that go up and around the intestines.
The duodenum is also shown; it is the first section of the small intestine.
The last section of the canal shown is the rectum , where feces are stored. Label the diagram.
5. There are two valves in the stomach. The cardiac sphincter is at the top of the stomach and prevents acid in the stomach from leaking into the esophagus. Draw this structure on the diagram and label it.
The second valve is at the lower end of the stomach, the pyloric sphincter, regulates the passage of partially digested food out of the stomach and into the small intestine. Draw this structure on the diagram and label it.
6. Identify the location of the cecum on the diagram, draw and arrow, and label it.
