A peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility is:
1. GIP
2. gastrin
3. secretin
4. CCK

Secretin will be secreted by the duodenal mucosa due to:
1. sodium bicarbonate in chyme
2. fats in chyme
3. peptones in chyme
4. hydrochloric acid in chyme

The secretion of which of the following will carry large amounts of sodium bicarbonate to neutralize the acidity of chyme in the small intestine?
1. pancreas
2. gall bladder
3. jejunum
4. salivary glands

Considered as the beginning of the large intestine, the blind end of the ascending colon is known as:

4. anal canal

All the following are functions of the human liver except:
1. It converts hemoglobin to bile pigments
2. It detoxifies blood by removing toxins
3. It produces urea from the breakdown of amino acids
4. It produces enzymes for digestion of food in the duodenum

Around 60 – 70 % of starch is broken down to maltose in the duodenum by:
1. pancreatic amylase
2. trypsin
3. maltase
4. salivary amylase

In humans, the energy source that provides energy the quickest is:
1. protein
2. carbohydrate
3. lipid
4. vitamins

Most of the parasympathetic supply to the alimentary canal is by:
1. vagus nerve
2. thoracic spinal nerves
3. lumbar spinal nerves
4. sacral spinal nerves

What prevents GER [gastro esophageal reflux]?
1. lower esophageal sphincter
2. sphincter of Oddi
3. esophageal hiatus
4. glottis

The part of the small intestine that has maximum length is the:
1. duodenum
2. jejunum
3. ileum
4. colon
