1. Where does intrinsic factor occur?: parietal cell
2. Which of the following stored feces prior to defecation?: rectum
3. Which of the following stores and concentrates bile?: duodenum
4. In what order from shortest to longest are the parts of the intestine?: duo-
denum, jejunum, ileum
5. What is the substrate of salivary amylase?: polysaccharides
6. Which hormone induces a watery secretion of bicarbonate from the pan-
creas?: secretin
7. What is the name of the digestive organ in which major absorption of water
occurs?: large intestine
8. Which substances reach the systemic circulation via lymph postabsorp-
tion?: lipids
9. Where is chemical digestion initiated in the alimentary canal?: oral cavity
10. Which layer of the stomach secretes mucus and is called the mucus
membrane?: mucosa
11. What is the sequence of the digestive process?: ingestion, digestion, absorp-
tion, defecation
12. Which enzyme catalyzes the disassociation of carbonic acid into hydrogen
and bicarbonate ions?: carbonic anhydrase
13. Which of the following are ways in which carbon dioxide is transported in
the blood?: all of the above
14. As increasing amounts of carbon dioxide enter the blood, bicarbonate ions
begins to accumulate within the red blood cells. As the concentration gradient
is established, bicarbonate ions move out of the red blood cells and into the
blood plasma. The electrical balance between the blood plasma and red blood
cells must be maintained; therefore, as one bicarbonate ion moves into the
plasma, so one negatively charged ion moves into a red blood cell from the
plasma. Which ion moves into the blood cell?: chloride
15. Which statement is true about carbohydrates?: they provide glucose that is
converted to energy
16. Which statement is true about fat? Choose 2 answers: it provides nine
calories per gram
it produces hormones
17. Which food type is a source of carbohydrates?: vegetables
18. Which element is a macronutrient?: protein
19. Which macronutrient supplies amino acids to the body when the macronu-
trient breaks down?: protein

37. Which salivary gland lies within the cheeks?: parotid
38. What is the main component of saliva?: water
39. Which structure forms the anterior border of the oral cavity?: lips
40. Which mastication muscle elevates and retracts the mandible?: temporalis
41. Which part of the pharynx is the most superior?: nasopharynx
42. In which part of the pharynx does air and food get mixed?: oropharynx
43. Which description matches the lower esophageal sphincter?: formed by a
portion of the diaphragm
44. Which phase of swallowing involves the contraction of the longitudinal
layer of the muscularis?: esophageal phase
