Dissection Questions – Respiratory and Digestive Systems
1. Are the cartilage rings of the human trachea complete or incomplete? ____________
2. Are the cartilage rings of the cat trachea complete or incomplete? ____________
3. Describe the location of the epiglottis and the vocal cords.
4.. Describe the appearance of the end of the trachea and the bronchial tree in the cat lung
after you have pushed away the lung tissue from the cartilage.
5. Describe the appearance of cat lung tissue as seen under the dissecting microscope.
Relate your observations under the microscope to what you know about alveolar
structure.

7. Where does the bile duct enter the duodenum?
8. Differentiate between mesentery and mesocolon. 2 points
9. a. How does the appearance of the villi differ in the duodenum and ileum? 2 points
b. How does the difference relate to function?
10. Does the cat have an appendix? ________
e. Draw a figure of the pancreas slide. Label islets of Langerhans and acinar cells.
Print and use a ruler. Use the 40X lens.
11. Draw an example of what you observed on the liver slide. Label central vein and
hepatocytes. Print and use a ruler.
