BIOS256 FINAL EXAM correct questions with verified answers
A+ grade
pancreas
- correct answer delivers pancreatic juice into duodenum via pancreatic duct to assist absorption
liver
- correct answer produces bile (bile salts) necessary for emulsification and absorption of lipids
gallbladder
- correct answer stores, concentrates, and delivers bile into duodenum via common bile duct
small intestine
- correct answer major site of digestion and absorption of nutrients and water in GI tract
Intestinal Glands
- correct answer secrete intestinal juice to assist absorption
absorptive cells
- correct answer digest and absorb nutrients
goblet cells
- correct answer secrete mucus
enteroendocrine cells
- correct answer secrete secretin (s), cholecystokinin (cck), and glucose-dependent insulinotropic
peptide
paneth cells
- correct answer secrete lysozyme (bactericidal enzyme) and phagocytosis
, Duodenal (Brunner's) glands
- correct answer secrete alkaline fluid to buffer stomach acids an dmucus for protection and lubrication
circular folds
- correct answer folds of mucosa that increase surface area for digestion and absorption
villi
- correct answer finger-like projections of mucosa that are sites of absorption of digested food and
increase surface area for digestion and absorption
microvilli
- correct answer microscopic, membrane-covered projections of absorptive epithelial cells that contain
brush-border enzymes and that increase surface area for digestion and absorption
Segmentation
- correct answer 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
Migrating Motility Complex
- correct answer 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.
Buffer Systems
- correct answer Bicarbonate, proteins, phosphate (chemical)
respiratory (exhalation of carbon dioxide)
renal - secretion of hydrogen into urine via PCT, reabsorbs or secretes bicarbonate
Glycolysis
- correct answer one glucose molecule is oxidized and two molecules of pyruvic acid are produced. Also
produces 2 ATP and 2 NADH + H
