If for some reason the parietal cells of the gut epithelium become partially non-functional, what is likely to happen?
1. The pH of stomach will fall abruptly.
2. Steapsin will be more effective.
3. Proteins will not be adequately hydrolyzed by pepsin into proteases and peptones.
4. The pancreatic enzymes, and especially trypsin and lipase, will not work efficiently.

Large intestine is called as “large” because:
1. It is longer than the small intestine
2. Its lumen is larger than that of small intestine
3. It absorbs a large amount of water
4. It is largely responsible for absorption of digested end products

The process of conversion of complex food substances to simple absorbable forms is called:
1. Mastication
2. Deglutition
3. Digestion
4. Assimilation

The structural and functional units of liver containing hepatic cells are:
1. Hepatic lobes
2. Hepatobiliary tree
3. Hepatic lobules
4. Hepatic sinusoids

The pancreatic acini:
1. Produce insulin and glucagon
2. Produce somatostatin
3. Secrete hydrolases
4. Store glucose and fats

The peptic or chief cells of the gastric mucosa secrete:
1. Mucucs
2. HCl
3. A proenzyme
4. Prokinetic hormone

The lower section of stomach that facilitates emptying the contents into the small intestine is called:
1. Cardia
2. Fundus
3. Corpus or body
4. Pylorus

The part of the small intestine where maximum absorption takes place is lined by:
1. Squamous epithelium
2. Cuboidal brush bordered epithelium
3. Columnar brush bordered epithelium
4. Transitional epithelium

The intestinal enzymes require an alkaline pH to act. This is accomplished by the secretions of all the following except:
1. Goblet cells
2. Brunner’s glands
3. Parietal cells
4. Pancreas

About what percentage of starch is hydrolysed by salivary amylase into maltose?
1. 30 – 40
2. 50 – 60
3. 60 – 70
4. 90 – 100
