Melanin
Bilirubin
Myoglobin
Hemoglobin
2. Which specialized channels allow mixed blood from branches of the portal vein and hepatic artery to pass alongside hepatocytes?
Bile canaliculi
Lymphatic ducts
Hepatic sinusoids
Central veins
3. A liver region needs a direct supply of oxygen-rich arterial blood. Which vessel provides it?
The common hepatic duct
The hepatic portal vein
The hepatic artery proper
The hepatic vein
4. Which set of structures forms the core of a typical portal triad?
A hepatic vein, central vein, and bile canaliculus
A portal vein branch, hepatic artery branch, and bile ductule
A portal vein branch, hepatic vein, and pancreatic duct
A central vein, lymph node, and cystic duct
5. Following a carbohydrate-rich meal, which process can hepatocytes use to help regulate blood glucose?
Concentrating bile by removing water
Releasing insulin directly into the blood
Converting glucose into glycogen for storage
Filtering glucose into urine
6. Bile from the right and left hepatic ducts first joins in which structure?
The pancreatic duct
The common bile duct
The cystic duct
The common hepatic duct
7. While examining a classical hepatic lobule, a student traces blood inward from structures at its perimeter. Where does that blood ultimately collect?
In a portal triad
In a bile ductule
In a branch of the hepatic artery
In the central vein
8. After nutrients are absorbed from the small intestine, which vessel carries most of that nutrient-rich blood toward the liver?
The hepatic vein
The inferior vena cava
The cystic artery
The hepatic portal vein
9. Where is most of the liver located in the body?
In the right upper abdomen, mainly beneath the diaphragm
In the left lower abdomen, beside the sigmoid colon
In the pelvic cavity, behind the urinary bladder
In the central chest, directly behind the heart
10. A surgeon examining the liver's visceral surface identifies the gateway where the portal vein and hepatic artery enter and bile ducts leave. What is this area called?
The falciform ligament
The ligamentum teres
The porta hepatis
The bare area
11. A histology slide shows a roughly hexagonal liver unit organized around a central vein. What is this unit called?
A classical hepatic lobule
A portal lobule
A hepatic acinus
A renal lobule
12. A meal contains a large amount of fat. What is bile's main digestive contribution in the small intestine?
It emulsifies fat into smaller droplets
It converts starch directly into glucose
It breaks proteins into individual amino acids
It supplies the main enzyme that digests triglycerides
13. On the liver's diaphragmatic surface, the falciform ligament marks the anatomical division between which lobes?
The caudate and quadrate lobes
The left and quadrate lobes
The right and caudate lobes
The right and left lobes
14. Which resident liver cells act as macrophages, helping remove microbes and cellular debris from sinusoidal blood?
Pancreatic acinar cells
Kupffer cells
Cholangiocytes
Gastric parietal cells
15. Why can surgeons sometimes remove a liver segment while preserving neighboring segments?
Each segment is enclosed in a completely separate fibrous capsule
Segments have relatively independent vascular inflow and biliary drainage
Only one segment receives blood from the portal vein
Neighboring segments are supplied solely by the gallbladder
16. Trace blood leaving the liver after it has passed through central veins and larger collecting veins. Which vessels carry it directly into the inferior vena cava?
The hepatic veins
The hepatic portal veins
The right and left hepatic ducts
The cystic arteries
