Question 1 |
Column I contains names of the sphincter muscles of the alimentary canal and column II contains their locations. Match them properly and choose the correct answer.
| Column I | Column II | ||
| A | Sphincter of ani internus | p | opening of hepatopancreatic duct into duodenum |
| B | Cardiac sphincter | q | between duodenum and posterior stomach |
| C | Sphincter of oddi | r | guarding the terminal part of alimentary canal |
| D | Ileocaecal sphincter | s | between esophagus and anterior stomach |
| E | Pyloric sphincter | t | Between small intestine and bowel |
A = r, B = q, C = s, D = p, E = t | |
A = q, B = t, C = p, D = s, E = r | |
A = r, B = s, C = p, D = t, E = q | |
A = s, B = r, C = p, D = q, E = t |
Question 2 |
The diagram of large intestine of man is given below. Identify the parts labelled A, B, C, D, E and F.
A = Caecum, B = Vermiform appendix, C = Sigmoid, D = Ascending colon, E = Transverse colon, F = Descending colon. | |
A = Sigmoid, B = Vermiform appendix, C = Ascending colon, D = Transverse colon, E = Descending colon, F = Caecum. | |
A = Sigmoid, B = Vermiform appendix, C = Descending colon, D = Transverse colon, E = Ascending colon, F = Caecum. | |
A = Caecum, B = Vermiform appendix, C = Ascending colon, D = Transverse colon, E = Descending colon, F = Sigmoid. |
Question 3 |
Liver the largest gland is associated with several functions. Which one of the following is stated incorrectly?
Stores glucose as glycogen | |
Manufactures bile, converts the amino groups to urea | |
Makes all the cholesterol that human body needs | |
Secrete hormone called gastric |
Question 4 |
Which one of the following statement is not correct about intestinal villi?
A multitudinous finger-like projections having many microvilli | |
Increase the internal surface area of the intestinal wall. | |
Supplied with capillaries and the lacteal vessels | |
Participate only in digestion of fats |
Question 5 |
The following list describes four major digestive enzymes. Which one of the following is incorrect?
Salivary amylase - Salivary glands - Mouth | |
Pepsin - Gastric glands - Stomach | |
Nuclease - Small intestine - Stomach | |
Lipase - Pancreas - Small intestine |
Question 6 |
Carrier ions like Na+ facilitate the absorption of substances like
Fructose and some amino acids | |
Amino acids and glucose | |
Glucose and fatty acids | |
Fatty acids and glycerol |
Question 7 |
Which one of the following is the correct matching of the site of action on the given substrate, the enzyme acting upon it and the end product?
| (1) Stomach: | Fats —Lipase—► micelles |
| (2) Duodenum: | Triglycerides —Trypsin—► monoglycerides |
| (3) Small intestine: | Starch —(α)Amylase—► Disaccharide (Maltose) |
| (4) Small intestine: | Proteins —Pepsin—► Amino acids |
(1) | |
(2) | |
(3) | |
(4) |
Question 8 |
If for some reason our goblet cells are non-functional this will adversely affect
Smooth movement of food down the intestine | |
Production of somatostatin | |
Secretion of sebum from the sebaceous glands | |
Maturation of sperms |
Question 9 |
What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?
Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin | |
Gastric juice will be deficient in chymosin | |
Gastric juice will be deficient in pepsinogen | |
In the absence of HCl secretion, inactive pepsinogen is not converted into the active enzyme pepsin. |
Question 10 |
A young infant may be feeding entirely on mother's milk which is white in colour but the stool which the infant passes out is quite yellowish. What is this yellow colour due to
Pancreatic juice poured into duodenum | |
Intestinal juice | |
Bile pigments passed through bile juice | |
Undigested milk protein casein |
Question 11 |
Bile contribution to digestion is
Nucleic acid metabolism | |
Phagocytosis | |
Emulsification of dietary lipids | |
Carbohydrate digestion |
Question 12 |
Name the hormone that stimulates the secretion of gastric juice.
Renin | |
Enterokinase | |
Enterogastrone | |
Gastrin |
Question 13 |
Bile salts act as activator of which enzyme?
Pepsinogen | |
Trypsinogen | |
Lipase | |
Pancreatic amylase |
Question 14 |
Aggregates of lymphoid tissue present in the distal portion of the small intestine are known as
Villi | |
Peyer’s patches | |
Rugae | |
Choroid plexus |
Question 15 |
Which one of the followings is not part of the large intestine?
rectum | |
colon | |
cecum | |
duodenum |

Please review que.3. Liver is the major site for cholesterol synthesis but not the sole site. Intestine is another significant contributor.
here in que 7 …..the final product is maltose and sight of action is small intestine …..bt in small intestine the last n final product is monosaccharide sooo the ans should be 4….and also if 3 is right then there should not be small intestine bt there should be ….buccal cavity
Please look at the name of the enzyme also. Amylase hydrolyses starch up to the stage of maltose or maltotriose. Further hydrolysis to glucose is catalysed by maltase.
nice pratice i had i liked the type of tricky questions asked
these questions were really tricky. i like such questions.i am confused in Q7
Its very helpful for medical entrance examinations..
