Left lobe of the liver
- C.
Ligament venosum
- D.
IVC
Correct Answer
D. IVCExplanation
The correct answer is IVC. The caudate lobe of the liver is positioned anterior and medial to the inferior vena cava (IVC). The IVC is a large vein that carries deoxygenated blood from the lower body to the heart. The caudate lobe is one of the four lobes of the liver and is located on the posterior surface of the liver. It is separated from the rest of the liver by the ligamentum venosum and is situated anteriorly and medially to the IVC.Rate this question:

- A.
Main portal vein
- B.
Porta hepatis
- C.
Ligament venosum
- D.
Left lobe of the liver
Correct Answer
A. Main portal veinExplanation
The caudate lobe is located at the posterior aspect of the liver, behind most structures. However, it is not posterior to the main portal vein.Rate this question:
-
- 13.
Major hepatic veins course between lobes, while major branches of portal veins course within segments (except prox. LPV).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the major hepatic veins run between the lobes of the liver, while the major branches of the portal veins run within the segments of the liver. This means that the hepatic veins carry blood out of the liver, while the portal veins bring blood into the liver. The exception mentioned, proximal left portal vein, indicates that it does not follow the usual pattern and may course differently.Rate this question:

Which is the largest lobe of the liver?
- A.
Right
- B.
Left
- C.
Quadrate
- D.
Caudate
Correct Answer
A. RightExplanation
The right lobe of the liver is the largest lobe because it accounts for about two-thirds of the liver's total mass. It is located on the right side of the body and is responsible for many important functions, including the production of bile, storage of glycogen, and detoxification of various substances. The left lobe, quadrate lobe, and caudate lobe are smaller in size compared to the right lobe.Rate this question:

The anterior segment of the right lobe contains
- A.
Right hepatic vein
- B.
Posterior branch or right portal vein
- C.
Anterior branch of right portal vein
- D.
Left hepatic vein
Correct Answer
C. Anterior branch of right portal veinExplanation
The anterior segment of the right lobe contains the anterior branch of the right portal vein. The portal vein carries nutrient-rich blood from the digestive organs to the liver. The liver then processes this blood before it is sent back to the heart. The right lobe of the liver is one of the two main lobes and is divided into segments. The anterior branch of the right portal vein supplies blood to the anterior segment of the right lobe, allowing for the delivery of nutrients and oxygen to this specific area of the liver.Rate this question:

What separates the right lobe from the medial segment of the left lobe?
- A.
Left hepatic vein
- B.
Right hepatic vein
- C.
Middle hepatic vein
- D.
Right portal vein
Correct Answer
C. Middle hepatic veinExplanation
The middle hepatic vein separates the right lobe from the medial segment of the left lobe. The liver is divided into lobes, and the middle hepatic vein runs between the right lobe and the medial segment of the left lobe, acting as a boundary between them.Rate this question:

In the caudate lobe, the venous blood drains directly into the IVC.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The caudate lobe is a segment of the liver located between the left and right lobes. It receives blood from both the hepatic artery and the portal vein. However, unlike the other liver lobes, the venous blood from the caudate lobe drains directly into the inferior vena cava (IVC) instead of going through the hepatic veins. This is due to its unique anatomical position and vascular supply. Therefore, the statement that venous blood drains directly into the IVC from the caudate lobe is true.Rate this question:
-
- 19.
What separates the left lobe from the caudate lobe?
- A.
Falciform ligament
- B.
Left portal vein
- C.
Left hepatic vein
- D.
Ligament venosum
Correct Answer
D. Ligament venosumExplanation
The ligament venosum separates the left lobe from the caudate lobe. The ligament venosum is a fibrous band that represents the remnant of the fetal ductus venosus, which shunted blood from the umbilical vein to the inferior vena cava. It is located on the posterior surface of the liver and runs along the inferior border of the caudate lobe, forming a clear boundary between the left lobe and the caudate lobe.Rate this question:
-
- 20.
Which lobe receives blood from both the right and the left portal veins?
- A.
Right
- B.
Left
- C.
Quadrate
- D.
Caudate
Correct Answer
D. CaudateExplanation
The caudate lobe is the correct answer because it receives blood from both the right and left portal veins. The portal veins carry nutrient-rich blood from the digestive organs to the liver, and the caudate lobe is one of the lobes of the liver that receives blood from both sides. This allows for efficient distribution of nutrients and processing of toxins in the liver.Rate this question:
