D. Hepatic ducts- Bile duct - Hepatopancreatic ampulla - Cystic duct -Gall bladder -Duodenum

Answer

To determine the correct sequence of the flow of bile from the liver, we need to follow the pathway that bile takes from its production in the liver to its eventual release into the small intestine. Here’s the step-by-step breakdown:

### Step-by-Step Solution:

1. **Bile Production in the Liver**: Bile is produced in the liver, which is the largest exocrine gland in the body. The liver has two lobes: the right hepatic lobe and the left hepatic lobe.

2. **Formation of Hepatic Ducts**: The right lobe of the liver releases bile through the **right hepatic duct**, while the left lobe releases bile through the **left hepatic duct**.

3. **Common Hepatic Duct**: The right and left hepatic ducts merge to form the **common hepatic duct**. This duct carries bile away from the liver.

4. **Cystic Duct from the Gallbladder**: The common hepatic duct connects to the **cystic duct**, which is the duct that leads to and from the gallbladder. The gallbladder stores bile.

5. **Common Bile Duct**: The common hepatic duct and the cystic duct combine to form the **common bile duct**. This duct transports bile to the duodenum.

6. **Hepatopancreatic Ampulla**: The common bile duct joins with the **pancreatic duct** (which carries pancreatic juice) to form the **hepatopancreatic duct**. This duct opens into the duodenum.

7. **Sphincter of Oddi**: The hepatopancreatic duct opens into the duodenum at the **ampulla of Vater**, which is regulated by the **sphincter of Oddi**. This sphincter controls the flow of bile and pancreatic juice into the small intestine.

### Final Sequence:
The correct sequence of the flow of bile from the liver is:
1. Right hepatic duct
2. Left hepatic duct
3. Common hepatic duct
4. Cystic duct (from the gallbladder)
5. Common bile duct
6. Hepatopancreatic duct
7. Duodenum (via the ampulla of Vater)
