Update
1. Secretin: decreases peristalsis
2. Gastric mixing and emptying: - Retropulsion
- Rate dependent on volume, osmotic pressure, and chemical composition
3. Stimulation of gastric secretion: -Eating
-Gastrin
-Paracrine pathways
-Acetylcholine
-Chemicals
--Ethanol, coffee, protein
4. intrinsic factor: makes the absorption of vitamin B12 happen
5. gastroferritin: binds Fe2+ and transports it to small intestine
6. phases of gastric secretion: 1. cephalic phase
2. gastric phase
3. intestinal phase
,7. Gastric juices include: - Pepsin, an enzyme that digests protein
- Other Enzymes
- Hydrochloric Acid
- Mucus
- Salts
- Water
8. acid plays what role in gastric secretion?: dissolves food fibers, act as bac-
tericide, convert pepsinogen to pepsin
9. Pepsin: Enzyme that breaks down proteins in the stomach
secreted by chief cells
10. Mucous in stomach: Protects stomach cells from gastric juices
, 11. small intestine: Digestive organ where most chemical digestion and absorption
of food takes place
12. Three sections of the small intestine: 1. Duodenum
2. Jejunum
3. Ileum
13. ileocecal valve: valve between the ileum of the small intestine and the cecum
of the large intestine
14. peritoneum: Double-layered membrane surrounding the abdominal organs
15. mesentery: a fused double layer of the parietal peritoneum that attaches parts
of the intestine to the interior abdominal wall
16. duodenum: first part of the small intestine- supplied by the gastroduodenal
artery
17. jejunum: second part of the small intestine-supplied by mesentery artery
18. ileum: the last and longest portion of the small intestine-supplied by mesentery
artery
19. myenteric plexus: controls gastrointestinal motility
20. Two layers of small intestine: longitudinal (outer) and circular (inner)
21. absorption through villi:: enterocytes
microvilli
brush border
lamina propria
lacteal
crypts of Lieberkühn
22. Intestinal Digestion and Absorption: -hydrochloric acid
-pepsin
-pancreatic enzymes
-intestinal enzymes
-bile salts
23. Crypts of Lieberkuhn: Glands located at the base of the intestinal villus
24. reflexes that inhibit intestinal motility: ileogastric reflex, intestinointestinal
reflux, gastroileal reflex
25. Peristalsis: Involuntary waves of muscle contraction that keep food moving
along in one direction through the digestive system.
26. large intestine: The last section of the digestive system, where water is ab-
sorbed from food and the remaining material is eliminated from the body
27. Parts of the large intestine in order: cecum, ascending colon, transverse
colon, descending colon, sigmoid colon, rectum, anal canal
28. teniae coli of the large intestine: three bands of longitudinal smooth muscle
in muscularis
