Study Notes
Gallbladder Overview
- A hollow, pear-shaped organ that stores and concentrates bile for digestion.
- Excretes bile into the small intestine, crucial for fat digestion.
Hepatic Ducts
- Right and left hepatic ducts collect bile from all bile ducts in the liver lobes.
- They facilitate bile transport from the liver to the gallbladder and small intestine.
Common Hepatic Duct
- Formed by the junction of right and left hepatic ducts.
- Key passageway for bile leaving the liver.
Cystic Duct
- Connects gallbladder to the common hepatic duct.
- Bile flows from the common hepatic duct into either the common bile duct or the cystic duct for storage in the gallbladder.
Common Bile Duct
- Formed by the union of the common hepatic duct and cystic duct.
- Delivers bile directly into the duodenum, aiding in digestion.
Hepatopancreatic Sphincter
- A muscular valve encircles the common bile duct, pancreatic duct, and duodenal ampulla.
- Maintains resting tension to prevent bile from entering the duodenum except during meals.
Duodenal Ampulla
- Located where the common bile duct penetrates the duodenum.
- Acts as a chamber for the meeting of the common bile duct and pancreatic duct, facilitating digestive enzyme release.
