SOLUTIONS : Chamberlain College of Nursing

delivers pancreatic juice into duodenum via pancreatic duct to assist absorption Correct Answer:
pancreas

produces bile (bile salts) necessary for emulsification and absorption of lipids Correct Answer:
liver

stores, concentrates, and delivers bile into duodenum via common bile duct Correct Answer:
gallbladder

major site of digestion and absorption of nutrients and water in GI tract Correct Answer: small
intestine

secrete intestinal juice to assist absorption Correct Answer: Intestinal Glands

digest and absorb nutrients Correct Answer: absorptive cells

secrete mucus Correct Answer: goblet cells

secrete secretin (s), cholecystokinin (cck), and glucose-dependent insulinotropic peptide Correct
Answer: enteroendocrine cells

secrete lysozyme (bactericidal enzyme) and phagocytosis Correct Answer: paneth cells

secrete alkaline fluid to buffer stomach acids an dmucus for protection and lubrication Correct
Answer: Duodenal (Brunner's) glands

folds of mucosa that increase surface area for digestion and absorption Correct Answer: circular
folds

finger-like projections of mucosa that are sites of absorption of digested food and increase
surface area for digestion and absorption Correct Answer: villi

microscopic, membrane-covered projections of absorptive epithelial cells that contain brush-
border enzymes and that increase surface area for digestion and absorption Correct Answer:
microvilli

type of peristalsis - alternating contractions of circular smooth muscle fibers that produce
segmentation and resegmentation of sections of small intestine, mixes chyme with digestive
juices and brings food into contact with mucosa for absorption Correct Answer: Segmentation

, Type of peristalsis: waves of contraction and relaxation of circular and longitudinal smooth
muscle fibers passing the length of the small intestine; moves chyme toward ileocecal sphincter.
Correct Answer: Migrating Motility Complex

Bicarbonate, proteins, phosphate (chemical)
respiratory (exhalation of carbon dioxide)
renal - secretion of hydrogen into urine via PCT, reabsorbs or secretes bicarbonate Correct
Answer: Buffer Systems

Krebs Cycle

oxidize NADH + H and FADH2, transfer electrons through series of carriers Correct Answer:
Electron Transport Chain

exergonic
break down macronutrients
occur in glycolysis, Krebs, and ETC Correct Answer: Catabolic reactions

endergonic
formation of peptide bonds between amino acids
building of fatty acids into phospholipids
linkage of glucose monomers to form glycogen Correct Answer: Anabolic reactions

Produce pancreatic juice
buffer acidic gastric juice in chyme
stops action of pepsin
creates proper pH for action of digestive enzymes
secretes inactive enzymes Correct Answer: Functions of the Pancreas

promotes secretion of gastric juice, increases gastric motility, promotes growth of gastric mucosa
stimulated by stomach distention, high pH
produced by G cells Correct Answer: Gastrin

stimulates secretion of pancreatic juice and bile that are rich in bicarbonate ions
stimulated by acidic chyme entering small intestine
produced by S cells Correct Answer: Secretin

stimulates secretion of gastric juice, ejection of bile, induces satiety
stimulated by partially digested proteins, triglycerides, and fatty acids that enter small intestine
produced by CCK cells Correct Answer: CCK

increases appetite
