Accepted Answer

Bile and pancreatic enzymes

Question 3

Which structure is responsible for the segmented appearance of the large intestine?

Accepted Answer

Haustra

Question 4

Accepted Answer

$$	ext{Portal triad} ightarrow 	ext{Central vein} ightarrow 	ext{Hepatic vein} ightarrow 	ext{Inferior vena cava} ightarrow 	ext{Right atrium}$$

Question 5

Which histological feature is most characteristic of the large intestine?

Accepted Answer

Numerous goblet cells in the mucosa

Question 6

A gallstone blocking the cystic duct would most directly prevent:

Accepted Answer

Bile release from the gallbladder into the common bile duct

Question 7

Which of the following is NOT a component of the portal triad in the liver?

Accepted Answer

Central vein

Question 8

If the main pancreatic duct is blocked, which of the following would most likely occur?

Accepted Answer

Decreased delivery of digestive enzymes to the duodenum

Question 9

Which of the following best describes the role of the hepatic portal system?

Accepted Answer

It transports nutrient-rich blood from the digestive tract to the liver for processing.

Question 10

Which of the following is the correct pathway for bile from its production to its entry into the duodenum?

Accepted Answer

$$	ext{Liver} ightarrow 	ext{Right/Left hepatic ducts} ightarrow 	ext{Common hepatic duct} ightarrow 	ext{Cystic duct} ightarrow 	ext{Gallbladder} ightarrow 	ext{Cystic duct} ightarrow 	ext{Common bile duct} ightarrow 	ext{Major duodenal papilla} ightarrow 	ext{Duodenum}$$

Question 11

Which of the following best explains why the large intestine contains numerous goblet cells?

Accepted Answer

To produce mucus that lubricates fecal material

Question 12

A patient with liver damage has impaired bilirubin processing. Which symptom is most likely to develop?

Accepted Answer

Jaundice (yellowing of the skin and eyes)

Question 13

Which of the following is a function of the taeniae coli in the large intestine?

Accepted Answer

They form haustra by contracting and creating pouches.

Question 14

Which of the following best describes the histological difference between the liver and pancreas?

Accepted Answer

The liver contains central veins and portal triads, while the pancreas contains acini and ducts lined with cuboidal cells.

Question 15

If the sphincter of Oddi fails to relax, which of the following is most likely to occur?

Accepted Answer

Bile and pancreatic juices cannot enter the duodenum, leading to digestive problems.

Question 16

Which of the following is the primary function of the colon?

Accepted Answer

Absorption of water and electrolytes

Question 17

Which of the following best describes the flow of bile from the liver to the gallbladder?

Accepted Answer

$$	ext{Liver} ightarrow 	ext{Right/Left hepatic ducts} ightarrow 	ext{Common hepatic duct} ightarrow 	ext{Cystic duct} ightarrow 	ext{Gallbladder}$$

Question 18

Which of the following is a distinguishing histological feature of the liver lobule?

Accepted Answer

A central vein surrounded by rows of hepatocytes and sinusoids

Question 19

Which of the following best describes the function of the acinar cells in the pancreas?

Accepted Answer

They secrete digestive enzymes into the pancreatic ducts.
