Amazing and beautiful explanation of physiology however it is very essential to note that bile after passing from common hepatic duct does not divert itself to cystic duct for bile storage rather ;thebilefromtheliverisdivertedintothegallbladderduetothehightoneinthesphincterofOddi and then bile regurgitates back to cystic duct and gets stored there :).
Years trying understanding this concept. I had a problem believing that cystic duct passes bile salts through it both in and out to gallbladder. Funny. Thank you
"..and the bile is squuuuiiiezed out of the gall bladder" i so loved that !! :D :D :D i wish you all the good in the world ! your explanations are just incredible ! hope is not lost! a very happy student says Thank you!
What mechanism stops the bile travelling from the liver to the common bile duct, instead of turning into the cystic duct? Is there some kind of valve or some such that prevents this occurrence?
I'm guessing that when no bile is needed in the duodenum, bile goes into the gall bladder through ductus cysticus because it has nowhere else to go. When needed though, bile is pressed upp from the gall bladder and bile which happens to arrive from the liver is also taken along for the ride so to say. Since the gallbladder is nothing but a storing place for bile, there is no need for it to go through the gallbladder first.
Qurat Ulain no it’s 10% of bilirubin that returns to the liver as urobilinogen via the portal vein which is then excreted by the kidney into the urine.
You are right. Although, what he said does not conflict with what you are saying. If you listen carefully, he says that the ilium is where the absorption of bile salts and fats occur.
Common means that it is shared, one collective duct for many ducts that goes into it. Many gall ducts from the liver are emptied into the common (or shared) hepatic duct.
