NU 110 Exam 3 Questions with Answers
1. What are the parts of the small intestine?: 1. Duodenum
2. Jejunum
3. Ileum
2. What is the function of the Duodenum?: It receives Chyme. It is where your gallbladder dumps bile via bile ducts.
3. What is the importance of the small intestine?: Site of nutrient absorption.
4. What is the function of the Ileum: It's an extension to make sure whatever nutrients were not absorbed have somewhere to go.
5. What is the direction of the large intestine?: Ascending colon, transverse colon, Desecending colon, sigmoid colon, Rectum. Anus.
6. Where does digestion start?: starts psychologically before food enters the mouth
7. What is the enzyme that digests/breaks down glucose?: Amylase
8. What is the mechanical part of chewing? What is CN for chewing? CN for swallowing?: -Mastication
-CN#5 Trigeminal= chewing
-CN#9 Glossopharyngeal= swallowing
9. What structure is involved in swallowing after mastication?: Esophagus
10. What sphincter at the beginning of the stomach prevents us from having heart burn(Dyspepsia)?: -LES=
lower esophageal sphincter or Cardiac Sphincter.
11. When you swallow, what substance is released into the stomach to break down food?: Hydrochloric Acid
(HCL acid)

, 12. What substance breaks down protein in the stomach?: Pepsin
13. What is the mechanical part of the stomach?: Churning
14. What is the name of the substance that the stomach makes from digestion?-
: Chyme passes through the pyloric sphincter and dups into the duodenum
15. What are the 2 additional enzymes that the pancreas secretes?: -Lipase (fats)
-pepsidase (proteins) (sometimes called trypsin)
16. Lipase calls on what to help break down large amounts of fat?: Gallbladder for the secretion of bile helps break down large
amounts of fat.
17. What is the role of Villi? Where can they be found?: -Absorbs small nutrients molecules from the digestive tract
-it only absorbs, carbs and proteins once broken down into the smallest possible units.
-found only in the small intestine mucosa
18. What organ makes bile? How?: Liver and it uses broken down RBC's and the chemicals secreted from lysis to it's storage unit (gallbladder)
19. What is the role of sodium bicarbonate?: Neutralizes chyme from the stomach, providing for optimal pancreatic function (produced in
pancreas)
20. What is the mechanical function of digestion?: Breakdown of nutrients
21. What is the process involved in the small intestine?: Absorption of nutrients
22. What structure is primarily responsible for the digestion of proteins?: Stomach
23. What structure starts with the digestion of carbohydrates?: Mouth
24. What structure is primarily responsible for the absorption of carbohydrates and proteins?: Villus capillary
(villi) (found in small intestine)
