1. What does the perisinusoidal space of Disse contain?

Choices:

• plasma
• lymph
• bile
• blood

Answers:

• plasma

Comments:

• Correct
• That's right! The space of Disse is the extracellular space between the hepatocytes and the sinusoidal endothelium. Plasma extravasates through the leaky walls of the sinusoids.

Question 2

Which of the following are, or may be, located in the portal area? Choose all that apply.

Choices:

• a bile ductule
• a branch of the hepatic artery proper
• nerve fibres
• a lymphatic vessel
• a branch of the hepatic portal vein
• a tributary of the hepatic vein

Answers:

• a bile ductule
• a branch of the hepatic artery proper
• nerve fibres
• a lymphatic vessel
• a branch of the hepatic portal vein

Comments:

• Correct
• That's right! A tributary of the hepatic vein is located in the centre of the liver lobule where it is called the central vein.

Question 3

Which of the following promote the release of bicarbonate-rich fluid from the intercalated ducts of the pancreas? Choose all that apply.

Choices:

• parasympathetic input
• secretin
• sympathetic input
• cholecystokinin

Answers:

• parasympathetic input
• secretin

Comments:

• Correct
• That's right! Parasympathetic input and secretin stimulate pancreatic duct cells to secrete bicarbonate-rich fluid.

Identify cell type A.

Choices:

• Hepatocytes
• Hepatocyte

Answers:

• Hepatocytes
• Hepatocyte

Comments:

• Correct
• That's right! Hepatocytes radiate outward from the central vein in a spoke-like fashion, they constitute the majority of the liver parenchyma.

Question 5

Identify B.

Choices:

• Central vein
• a central vein

Answers:

• Central vein
• a central vein

Comments:

• Correct
• That's right! The central vein can be found within the centre of a liver lobule.
• Continue

Question 6

Identify space C.

Choices:

• Sinusoid
• hepatic sinusoid

Answers:

• Sinusoid
• hepatic sinusoid

Comments:

• Correct
• That's right! The hepatic sinusoids are lined by endothelium and are found between the hepatocytes.
• Continue

Question 7

Identify cell type D. Be specific.

Choices:

• Kupffer cell
• a Kupffer cell

Answers:

• Kupffer cell
• a Kupffer cell

Comments:

• Correct
• That's right! Kupffer cells can be found within the hepatic sinusoids, patrolling these areas and phagocytose debris such as old RBCs.
• Continue

Question 8

Identify A.

Choices:

• Hepatic arteriole

Answers:

• Hepatic arteriole

Comments:

• Correct
• That's right! The hepatic arteriole is a branch of the hepatic artery proper and is one of the three constituents that make up the portal triad. Identify it by the smooth muscle in its wall and the RBCs in its lumen.
• Continue

Question 9

Identify B.

Choices:

• Bile ductule

Answers:

• Bile ductule

Comments:

• Correct
• That's right! The bile ductule, a branch of the bile duct, is lined by simple cuboidal epithelium and is one of the main three constituents of the portal triad. Identify it by its cuboidal epithelium and the absence of RBCs in its lumen.
• Continue

Question 10

Identify C.

Choices:

• Portal venule

Answers:

• Portal venule

Comments:

• Correct
• That's right! The portal venule is a branch of the hepatic portal vein and can be easily identified as a component of the portal triad due to its large lumen. Also, RBCs may be present it its lumen, which is lined by simple squamous endothelium, and smooth muscle is absent from its wall.
• Continue

Question 11

Identify A.

Choices:

• pancreatic islet
• islet of langerhans

Answers:

• pancreatic islet
• islet of langerhans

Comments:

• Correct
• That's right! A pancreatic islet consists of a distinct, spherical ball of endocrine cells that stain paler than the surrounding exocrine cells.
• Continue

Question 12

Identify B.

Choices:

• pancreatic acinus
• acinus

Answers:

• pancreatic acinus
• acinus

Comments:

• Correct
• That's right! A pancreatic acinus consists of a group of exocrine cells secrete their products, pancreatic proenzymes, into the lumen of the acinus.
• Continue

Question 13

Identify cell type C.

Choices:

• acinar cell

Answers:

• acinar cell

Comments:

• Correct
• That's right! Pancreatic acinar cells form spherical structures called acini. They are exocrine cells that secrete their products, pancreatic proenzymes, into the lumen of the acinus.
