EXERCISE 38: ANATOMY OF THE DIGESTIVE SYSTEM
Be able to define digestion and absorption. What structures make up the
alimentary canal or gastrointestinal tract? What structures are accessory
organs?
What are the four basic tunics or layers that are consistent throughout the
entire GI tract?
On the models in class and the cat identify where possible:
Oral cavity - hard palate, soft palate, uvula, incissors, cuspids (or canines)
and molars, review the tonsils, tongue
Salivary glands- parotid, submandibular, sublingual
Esophagus, stomach ( cardiac, fundic, body and pyloric regions, pyloric
sphincter, lower esophageal or cardiac sphincter), small intestine (duodenum,
jejunum, ileum), ileocecal valve, large intestine (cecum, vermiform appendix,
ascending colon, hepatic or right colic flexure, transverse colon, splenic or
left colic flexure, descending colon, sigmoid colon, rectum, anus).
Accessory organs:
Pancreas (head, body, tail, pancreatic duct), liver (right, left, caudate and
quadrate lobes, falciform ligament, common hepatic duct), gall
bladder(cystic duct, common hepatic duct), mesentery
Structure of the tooth: enamel, dentin, pulp cavity, root canal, crown, neck root.
Slides:
Pancreas - identify pancreatic islets and exocrine cells
EXERCISE 39: CHEMICAL AND PHYSICAL PROCESSES OF DIGESTION
In lab perform Activity 5: observing movement and sounds of digestion.
Do the Physio Ex computer simulations for chemical and physical processes of
digestion and be prepared to answer questions about your results. (page p-86 in
your lab manual)
Understand what chemical processes take place in which part of the digestive
system as shown by the handout to be given out in lab.
