Cat Dissection Lab Report:
Respiration:
1. Are the cartilaginous rings in the cat trachea complete or incomplete?
2. Compare the number of right and left lung lobes in cats and humans.
3. Using what you know about cat muscles, do you expect the same muscular
involvement as in humans? Why or why not?
4. Describe the position of the heart relative to the lungs. How does this relate
to blood flow through the pulmonary circuit?
Digestion:
1. What types of structures do you see in the mesentary? Other than
providing support for the intestine, what other functions does the
mesentery have?
2. Are there any obvious differences in the external anatomy of the small
intestine from one end to the other? Internally, is there a difference in
the villi between the duodenum and ileum? What functional reason
exists for this?
3. Research and briefly explain the hepatic portal system. How does this
relate to liver function?
4. What is the function of the rugae found in the stomach?
5. Explain the differences in dental formulas between cats and humans.
Explain the differences in tongue papillae in cats and humans.
Urinary:
1. How does the position of the kidneys in the cat relate to their position in
humans?
2. How does the site of urethral emptying in the female cat differ from its
termination point in the human female?
3. What gland encircles the neck of the bladder in the male? What is its
function?
4. Describe the path urine would follow from its formation to its elimination
from the body in the cat and in the human.
Reproduction:
1. Explain the difference between the cat uterus and the human uterus both
structurally and physiologically.
2. Approximately how long is the vagina of the cat? What is the urogenital
sinus?
3. Compare the prostate glands, bulbourethral glands and seminal vesicles
in cats and humans. What similarities and differences are there both
anatomically and physiologically?
4. Briefly describe how the embryonic origins of both the male and female
reproductive systems relate to each other.
