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
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.
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
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
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
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
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|
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
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.
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
Bile pigments passed through bile juice
Undigested milk protein casein
Bile contribution to digestion is
Nucleic acid metabolism
Emulsification of dietary lipids
Name the hormone that stimulates the secretion of gastric juice.
Bile salts act as activator of which enzyme?
Aggregates of lymphoid tissue present in the distal portion of the small intestine are known as
Which one of the followings is not part of the large intestine?

very good and high level questions which made me to understand the concepts in deep.
but i have a doubt in q.no.6 why is option a is correct and option b is wrong
Regarding que.6, absorption of fructose doesn’t require sodium ions. Sodium ions are required only for absorption of glucose, galactose and amino acids.
Fructose is absorbed through facilitated diffusion…not by active or passive diffusion.Na is acting as a carrier
