The function of human gall bladder would be that it:
1. Synthesizes bile
2. Stores and concentrates bile
3. Secretes secretin
4. Secretes cholecystokinin
Identify the correct statement:
1. Cabohydrate digestion begins in the stomach
2. Polsaccharides are broken down to monosaccharides by amylase
3. Disaccharides are actively transported across the epithelium of the small intestine
4. Final luminal digestion of carbohydrates produces monosaccharides
Identify the correct statement regarding lipid digestion and absorption:
1. Most lipids are asorbed without digestion as they are not macromolecules
2. The products of lipid digestion are resynthesized into triglycerides in intestinal epithelial cells
3. The products of lipid digestion diffuse into capillaries in the vicinity of the intestinal epithelium
4. The products of lipid digestion travel in the circulatory system in the form of micelles
Identify the correct statement regarding the transport of the absorbed products of fat digestion:
1. Free fatty acids and monoglycerides are transported to the liver via the hepatic portal vein
2. Triglycerides are transported through the lymphatics in lipoproteins called LDL
3. Triglycerides are transported through the lymphatics as part of lipoproteins called chylomicrons
4. Free fatty acids and monoglycerides are transported through the lymph as part of lipoproteins called chylomicrons
Emulsification of fats occurs in small intestine and it:
1. Results in the formation of small fat droplets
2. Depends upon the polar structure of bile salts
3. Results in the formation of chylomicrons
4. Depends upon the polar structure of bile pigments
Intrinsic factor helps in the absorption of:
1. Amino acids
2. Sodium
3. Glucose
4. Vitamin B-12
During deglutition, what allows the food to enter the stomach?
1. Pyloric sphincter
2. Ileocecal sphincter
3. Epiglottis
4. Lower esophageal sphincter
HCl in stomach is the function of ___ cells that contain an enzyme called ___ that catalyzes the reaction between ______________ and water.
1. Chief; carbonic esterase; carbon dioxide
2. Parietal; carbohydrase; bicarbonate
3. Parietal; carbonic anhydrase; carbon dioxide
4. Goblet; carbonic anhydrase; bicarbonate
Identify the incorrect statement:
1. Increasing acidity in the stomach stimulates endocrine cells in the gastric epithelium to produce somatostatin that inhibits further HCl secretion
2. HCl production increases in response to carbohydrates entering the stomach
3. HCl secretion is inhibited when acidity increases in the small intestine
4. Gastrin, histamine, and acetylcholine all act to increase HCl secretion
Enterokinase:
1. | stimulates bicarbonate secretion by the pancreas |
2. | stimulates secretion of gastrin by the stomach |
3. | converts trypsinogen into trypsin |
4. | converts pepsinogen into pepsin |
