| Term | Definition |
|---|
| Function | stores and concentrates bile before it is excreted into the small intestine (bile storage and bile modification) |
| Location | in a fossa in the visceral surface of the right lobe of the liver |
| Three regions | fundus, body, neck |
| Cystic duct | leads from gallbladder toward porta hepatis; where bile travels for storage |
| Porta hepatis | where common hepatic duct and cystic duct unite and form common bile duct |
| Hepatopancreatic sphincter | muscular sphincter at duodenum, surrounds lumen of common bile duct and duodenal ampulla; contraction prevents bile from entering small intestine and bile enters cystic duct |
| Common bile duct | formed by common hepatic duct and cystic duct |
| Amount of bile stored | gallbladder can contain 40-70 ml of bile |
| Bile composition | will gradually change as it remains in gallbladder; water is absorbed from bile so bile becomes more concentrated |
| Hormone cholecystokinin (CCK) | stimulates ejection of bile; released into bloodstream at duodenum when chyme arrives with alot of lipids and partially digested proteins; causes relaxation of hepatopancreatic sphincter and contraction of gall bladder |
