  1. Sublayers of the Mucosa (if none are present answer "none").Where is this layer located?
    Epithelium, Lamina Propria (Loose Areolar Connective Tissue), and Muscularis Mucosae; this is the innermost layer.
  2. Sublayers of the Submucosa (if none are present answer "none").
    None.
  3. Sublayers of the Muscularis Externa (if none are present answer "none"). How is this layer modified in the stomach?
    Circular Layer and Longitudinal Layer; it is modified in the stomach with an extra layer called the Oblique Layer (used in peristalsis).
  4. Sublayers of the Serosa or Adventitia (if none are present answer "none"). Where is this layer located?
    Epithelium and Connective Tissue; it is the outermost layer.
  5. The tubelike digestive system canal that extends from the mouth to the anus is known as the __?__ canal of the __?__ tract.
    Alimentary Canal; Gastrointestinal (GI) Tract
  6. Are the liver, pancreas, and salivary glands part of the Alimentary Canal? If not what are they?
    No, they are Accessory Organs.
  7. What type of epithelium is present in the trachea?
    Pseudostratified Ciliated Columnar Epithelium
  8. What type of epithelium is present in the alveoli of the lungs?
    Simple Squamous Epithelium
  9. What type of epithelium is present in the esophagus?
    Keratinized Stratified Squamous Epithelium
  10. What type of epithelium is present in the stomach?
    Simple Columnar Epithelium
  11. What type of epithelium is present in the small intestines?
    Simple Columnar Epithelium
  12. What are the extrinsic salivary glands? Where are they located? What type of enzyme do they secrete?
    Parotid, Submandibular, and Sublingual Glands; located outside the mouth; secrete Amylase.
  13. What are the intrinsic salivary glands? Where are they located? What enzyme do they secrete?
    Buccal Glands; located inside the mouth; secrete Amylase.
  14. What are the three subdivisions of the pharynx? Which one is not part of the digestive system?
    Nasopharynx (not part of digestive), Oropharynx, and Laryngopharynx.
  15. What kind of cartilage make up the rings of the trachea?
    Hyaline Cartilage
  16. What layers are missing in the trachea that the esophagus have and what does it have instead?
    The trachea does not have a muscularis mucosae and a muscularis externa instead it has hyaline cartilage surrounded by 2 layers of perichondrium on either side.
  17. Does the liver produce bile or store bile?
    Produces bile (gallbladder stores bile).
  18. Is the pancreas an exocrine or endocrine organ?
    Both exocrine and endocrine.
  19. What are the exocrine cells of the pancreas? What do they secrete?
    Acinar cells; secrete buffer to neutralize stomach contents.
  20. What are the endocrine cells of the pancreas? What do they secrete?
    Islets of Langerhans; secrete insulin and glucagon. 
  21. What is the gastroesophageal junction?
    Junction where food starts to enter the stomach from the esophagus.
  22. What are the four parts of the stomach (in order)?
    Cardia region, Fundus, Body, and Pyloric region.
  23. What are the three parts that make up the small intestines (in order)?
    Duodenum, Jejunum, and Ileum.
  24. What is the ileocecal valve?
    Intersection of small and large intestine (junction between ileum of the small intestine and the cecum of the large intestine).
  25. What are the four parts that make up the large intestines (in order)?
    Cecum, Colon (ascending, transverse, descending, sigmoid), Rectum, and Anal Canal (leads to anus).
  26. What is the order of the types of colon in the large intestines?
    Ascending, Transverse, Descending, and Sigmoid.
  27. What canal leads to the anus?
    Anal canal
  28. How are the number of lobes on the lungs of cats different from humans?
    Cats' right lung has 4 lobes and the left 3 lobes. Humans' right lung has 3 lobes and the left has 2.
  29. What is the greater omentum?
    Serous membrane attached to greater curvature of stomach that covers the abdominal contents.
  30. What is the lesser omentum?
    Serous membrane attached to lesser curvature of stomach that connects the stomach the liver.
