Question

Consider the following statements each with one or two blanks.
(i) The bile duct and the pancreatic duct open together Into the duodenum as the (1) which is guarded by a sphincter called the (2) .
(ii) (3) is a proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins.
(iii) Fatty acids and glycerol being insoluble, cannot be absorbed into the blood. They are first incorporated into small droplets called (4) which move into the intestinal mucosa. They are re-formed into very small protein coated fat globules called the (5) which are transported into the lymph vessels (lacteals) in the villi.
Which of the following options gives the correct fill ups for the respective blanks in the above statements?

• A. (1) - common bile duct, (2) - sphincter of Boyden, (3) - Pepsin
• B. (3) - Rennin, (4) - chyme, (5) - micelles
• C. (1) - Common hepato-pancreatic duct, (2)- sphincter of Oddi, (4) - micelles, (5)- chylomicrons
• D. (3) - Casein, (4) - chylomicrons, (5) - micelles

Answer 1

Answer: (C)

(1) - Common hepato-pancreatic duct, (2)- sphincter of Oddi, (4) - micelles, (5)- chylomicrons

C. (1) - Common hepato-pancreatic duct, (2)- sphincter of Oddi, (4) - micelles, (5)- chylomicrons.

Solution: The bile duct and the pancreatic duct open together Into the duodenum as a common pipe called the Common hepato pancreatic duct and it is guarded by sphincter of Oddi. Renin is a proteolytic enzyme that digests milk proteins in infants. Fatty acids are converted into small droplets called micelles that are later digested by the lipase after they have formed chylomicrons in villi.

So the correct answer is " (1) - Common hepato-pancreatic duct, (2)- sphincter of Oddi, (4) - micelles, (5)- chylomicrons.".
