Trace the passage of bile juice stored in the gal bladder into the lumen ofduodenum.

Options

A. Cystic duct `to` common bile duct `to` hepatopancreatic duct `to` lumen of duodenum
B. Hepatic duct `to` common bile duct `to` hepatopanereatic duct` to` lumen ofduodenumn
C. Bile canaliculi `to`hepatic duct`to` common bile duct`to`cystic duct`to`lumen of duodemum
D. Hepatic ducts`to`bile canaliculi`to`cystic duet`to` hepatopancreatic duct to` lumen of duodenum

Answer

**Step-by-Step Solution:**

1. **Production of Bile Juice**: Bile juice is produced in the liver, specifically in the hepatic lobules, which are the structural and functional units of the liver. Hepatic cells within these lobules synthesize bile.

2. **Storage of Bile Juice**: Once produced, bile juice is stored and concentrated in the gallbladder, which is a thin muscular sac located beneath the liver.

3. **Cystic Duct**: The bile juice leaves the gallbladder through a duct known as the cystic duct. This duct is responsible for transporting bile from the gallbladder.

4. **Formation of Common Bile Duct**: The cystic duct merges with the hepatic duct (which carries bile from the liver) to form the common bile duct. This duct serves as a pathway for bile to enter the small intestine.

5. **Pancreatic Duct**: The pancreatic duct, which carries pancreatic juice from the pancreas, also plays a role in digestion.

6. **Common Hepatopancreatic Duct**: The common bile duct (from the gallbladder and liver) joins with the pancreatic duct to form the common hepatopancreatic duct.

7. **Entry into Duodenum**: The common hepatopancreatic duct opens into the lumen of the duodenum, which is the first part of the small intestine. This is where bile juice and pancreatic juice are released to aid in digestion.

**Final Passage Summary**:
- Bile is produced in the liver → stored in the gallbladder → exits through the cystic duct → combines with the hepatic duct to form the common bile duct → joins with the pancreatic duct to form the common hepatopancreatic duct → opens into the duodenum.
