Fetal Pig Dissection Questions
Jones
These questions are designed to help you study and remind you that you need to know more than just
the names and locations of the structures. Each night, you should do the sections of questions that
correspond to the dissection done that day. This will be collected on the day of the test!
Dissection 1 – External Features and Oral Cavity
1. What purpose do the salivary glands serve in digestion? What is the name of the enzyme produced?
Is this mechanical or chemical digestion?
2. What purpose does the tongue serve in digestion? Is this mechanical or chemical digestion?
3. What is the function of the epiglottis?
4. What is peristalsis? What type of muscle is responsible for this action?
5. Explain how you are going to be able to tell the difference between the entrances to the esophagus
versus the entrance to the trachea.
6. What is the function of the external nares?
7. What sex of the pig is identified by a urogenital papilla?
8. What does the term urogenital papilla imply about the organism’s urogenital system?
9. What is the opening to the penis called?
10. What is the scientific name of the ear? What type of tissue makes up the ear to give it its rigid
nature?
11. What is the scientific term for nipples?
12. The nipples on a male are not functional and are considered to be reduced in size; therefore, what
evolutionary term can be given to the male nipples?

16. What is the function of rugae?
17. What is the name of the fluid in the stomach that consists of partially digested food and chemicals
released to aid in digestion?
18. What is the function of mucus production in the stomach?
19. Name 3 functions of HCl in the stomach.
20. What is the name of the inactive form of the enzyme produced in the stomach that aids in protein
digestion? What activates it? What is the name of the active form?
21. What is the job of the esophageal sphincter?

26. Another function of the liver is to _______ blood.
27. What is the function of pancreatic amylase? Where is it secreted?
28. What chemical does the pancreas produce that allows sugars to enter your cells after they are
absorbed into the blood stream?
29. What is the function of sodium bicarbonate? What makes it? Where is it secreted?
30. The pancreas also produces enzymes (we didn’t name them specifically) to aid in the chemical
digestion of _______?
31. What is the function of lipase? What secretes it and where is it secreted?
32. What is the function of sucrase, lactase, and maltase? What produces these enzymes?

44. Where are gases exchanged in the pulmonary circuit?
45. Arteries carry oxygen _______ blood ________ the heart.
