Anatomy and Physiology
Cat Dissection Unit Spring 2012
Dissection Team Structure/Function Systems Table I
Lab Assignment: You and your lab partners must be able to locate EACH of the
structures listed below on your cat specimen. In addition, EACH student must learn the
function of each structure. Each Dissection Team must create a three-column word
processed table as follows and fill it in with the researched information. (Note: This will
count as a group lab grade. Although ONLY one copy of the table must be submitted to
the teacher, EACH student should maintain a copy for him/herself to use as reference.)

Below is the list of structures to include in your Structure/Function Systems Table I
for the Digestive and Respiratory Systems and the Associated Vascular Structures.
Please clearly indicate the separate digestive and respiratory systems structures in
your Table.
Ventral Body Cavities
1. Thoracic cavity
2. Abdominopelvic cavity
3. Pericardial cavity
Digestive System
1. hard palate
2. soft palate
3. palatine tonsils
4. epiglottis
5. glottis
6. esophagus
7. cardiac stomach (fundus)
8. pyloric stomach
9. pyloric sphincter
10. spleen
11. mesentery
12. greater omentum
13. falciform ligament
14. pancreas
15. gall bladder
16. cystic duct
17. hepatic duct
18. common bile duct
19. duodenum
20. jejunum
21. ileum
22. ascending colon
23. transverse colon
24. descending colon
25. rectum
26. greater and less curvature of the stomach
27. cecum
Associated Vascular Structures of Digestive System:
1. External jugular vein
2. transverse jugular vein
3. hepatic portal vein which includes the superior mesenteric and gastrosphlenic veins
4. coronary vein
5. posterior vena cava
7. superior mesenteric artery
8. inferior mesenteric artery
6. celiac artery
** Name all lobes of liver: Left medial lobe, left lateral lobe and on the right are:
quadrate lobe, right medial lobe, right lateral lobe and caudate lobe.
Respiratory System Structures:
1. trachea
2. larynx
3. thyroid cartilage
4. diaphragm
5. right and left principal (primary) bronchi
6. Three Lobes of left lung = Anterior, medial, and posterior
7. Three Lobes of right lung = Anterior, medial and posterior. Note: The posterior lobe
is further subdivided to include an Accessory Lobe.
Associated Vascular Structures of Respiratory Systems:
1.
Urogenital System
1. kidney
2. ureter
4. urethra (unable to see)
5. adrenal glands
3. urinary bladder
Female Reproductive System
1. Ovary
4. suspensory ovarian ligament
7. cervix
2. right and left horn of uterus
5. uterus
3. mesometrium
6. vagina
Note: The uterine tubes of the human female are comparatively much greater in length.
The uterus in the human is not Y-shaped, but resembles the shape of a pear, instead. The
constricted part of the uterus is known as the cervix. The junction of the uterus and
vagina is a distinct separation between the two organs in the human.
Male Reproductive System
1. Spermatic cord
2. Testis
3. Head of epididymis
4. vas deferens
5. prostate gland
6. penis
7. glans penis
8. cremasteric pouch
Note: The human penis is not contained within a sheath as in the cat, but hangs freely
from its attachments to the pubic symphysis by way of the crura (tough bands of
connective tissue).
Good Luck.
