Considered as the beginning of the large intestine, the blind end of the ascending colon is known as:
1. cecum
2. vermiform appendix
3. rectum
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

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 incorrect statement:
1. Constipation is caused by decreased motility in the large intestines
2. Diarrhea may result from decreased fluid absorption in the large intestines
3. A high intake of dietary fiber reduces the risk of constipation because it increases distension and motility in the large intestines
4. Bacterial diarrhea results from a bacterial toxin that blocks water channels in the cells of the large intestines
