3. Fetal Pig Dissection – Digestive System
A. Using the posterior Fetal Pig Outline, draw and label the digestive system from
**Figure 2-5. Be sure to include:
1. stomach
8. spleen
2. pylorus
9. beginning of jejuno-ileum
3. gall bladder
10. duodenum
4. colon
11. pancreas
5. decending colon
12. common bile duct
6. rectum
13. caecum
7. liver
14. small intestine
B. The Dissection: Read pages **42 and 44 in the manual.
1. Cut and remove digestive organs, keeping them attached to each other the best
you can.
- Begin caudal of the diaphragm. Find and cut esophagus first. Cut and
pull slowly on the connective tissue and organs.
- Lift out: liver, stomach, pancreas, small intestine,
and large intestine (colon). Keep it all intact!
-Cut as far down the descending colon as possible.
- Keep the entire digestive tract together and connected.
2. Once the entire digestive track is removed, you must begin to carefully cut
the mesentery holding the intestines together. Move slowly and cut
without damaging the intestines. You can now answer question #4.
3. Look at the liver, find the gall bladder and examine the stomach.
4. Locate the duodenum jejunum and ileum found in the small intestine.
5. Identify the ascending (spiral), transverse, and descending colon. Find and
identify the caecum.
C. Answer the Questions: (Question & Answer format)
1. Name 2 major organs that produce digestive enzymes. Name the enzymes.
2. Look at the stomach and describe its shape?
3. How many lobes does the liver have?
4. What is the total length of the digestive system in centimeters?
5. What is the function of the pyloric and cardiac valves in the stomach?
6. What activity occurs in the duodenum, jejunum and ileum of the intestine?
