The task is to label the parts of the liver anatomy using the provided word bank. Below is the solution with explanations for each labeled part:
Word Bank:
- Hepatic vein
- Cystic duct
- Hepatic portal vein
- Hepatic artery
- Teres ligament
- Aorta
- Left lobe
- Right lobe
- Gallbladder
- Inferior vena cava
- Common duct
- Hepatic duct
- Falciform ligament
Solution:
1.
Top Left (Blue Circle):
Hepatic artery
- The hepatic artery supplies oxygenated blood to the liver.
2.
Top Middle (Red Circle):
Hepatic portal vein
- The hepatic portal vein carries nutrient-rich blood from the digestive tract to the liver for processing.
3.
Top Right:
Inferior vena cava
- The inferior vena cava is a large vein that returns deoxygenated blood from the lower body to the heart.
4.
Middle Left:
Left lobe
- The left lobe is one of the two main lobes of the liver.
5.
Middle Right:
Right lobe
- The right lobe is the larger of the two main lobes of the liver.
6.
Bottom Left:
Gallbladder
- The gallbladder stores and concentrates bile produced by the liver.
7.
Bottom Middle:
Cystic duct
- The cystic duct connects the gallbladder to the common bile duct, allowing bile to flow between them.
8.
Bottom Right:
Common duct
- The common duct (also known as the common bile duct) carries bile from the liver and gallbladder to the small intestine.
9.
Center Bottom:
Hepatic duct
- The hepatic duct carries bile from the liver to the common bile duct.
10.
Falciform Ligament:
Falciform ligament
- The falciform ligament is a connective tissue structure that attaches the liver to the anterior abdominal wall and separates the right and left lobes of the liver.
11.
Teres Ligament:
Teres ligament
- The teres ligament is a fold of peritoneum that helps suspend the liver in place.
12.
Aorta:
Aorta
- The aorta is the largest artery in the body, carrying oxygenated blood from the heart to the rest of the body. It is visible near the liver but not directly part of the liver's anatomy.
Final Labeled Diagram:
- Top Left: Hepatic artery
- Top Middle: Hepatic portal vein
- Top Right: Inferior vena cava
- Middle Left: Left lobe
- Middle Right: Right lobe
- Bottom Left: Gallbladder
- Bottom Middle: Cystic duct
- Bottom Right: Common duct
- Center Bottom: Hepatic duct
- Falciform Ligament: Falciform ligament
- Teres Ligament: Teres ligament
- Aorta: Aorta
Explanation:
Each part of the liver has a specific function:
-
Liver Lobes: The liver is divided into the right and left lobes, which perform various metabolic functions.
-
Blood Supply: The hepatic artery and hepatic portal vein supply blood to the liver, while the hepatic veins drain blood away.
-
Biliary System: The gallbladder, cystic duct, hepatic duct, and common duct are part of the biliary system, responsible for storing and transporting bile.
-
Support Structures: The falciform and teres ligaments provide structural support to the liver.
This labeling exercise helps understand the anatomical relationships and functions of the liver and its associated structures.
