But wait! What makes the Sphincter of Oddi close? And, what makes it open? Does it react the same as that little door from the stomach to the esophagus? You‘Re great Gil--you make all this information easy to digest.
Hi Bronwyn! As with most of the tissues related to digestion, the enteric nervous system is the master of sphincter dilations, and cueing of all of the important moments related to digestion south of the diaphragm! Your gut truly has a mind of its own, and that's a very good thing, as if we had to think through all that we'd be doomed haha :)
@Gil Hedley and @Bronwyn Doyle - May I add, the sphincters as you mention are part of a system and orchestrate the motility of substances we take in for the proper digestion, assimilation, absorption, and elimination based on the body's intelligence; and often what I see manually is when one is struggling , they all struggle to compensate for the struggle.....because they are all part of the same orchestra.....some if the drums are off beat, the rhythm is off and the rest of the orchestra or symphony may be a better word.....don't make good sound....or sound decisions are off and the body can do this for a while until it can't....and hopefully the human living in the body of the not good sound listens and makes the right choices and right help to get things back on rhythm in time.....or one of the members of the symphony will be missed. Thanks Gil
This video is mind-blowing, I never knew this was how bile was released, so interesting! I just watched another video explaining that a hormone called cholecystokinin which is produced as a result of digestion causes both the gallbladder to contract, squeezing out bile and also the Sphincter of Oddi to relax, allowing bile to flow out into the small intestine
Bravo. Your work is a real living anatomy. I've never understood biile like that. Body's are amazing, and you're an inspiration to feel it. Vincent old bodyworker
I'm a 4th year medical student and I never learned this in medical school! It's only when studying for my biggest cumulative exam of medical school that I realized I had no explanation as to how bile makes its way INto the bile duct. Thanks a bunch Dr. Gil.
Wow! Just Wow! Gil you are Amazing! It is just so much fun to be in your company through these videos and learn about this miraculous Human form that we all have gift of. My partner is getting through some tuff time right now. She was diagnosed with Fatty Liver Disease(pharmaceuticals suppressed her condition for years I suspect) some very serious breathing issues(literally unable to breathe).She is unable to eat anything, she is hungry but afraid of eating because her body didn't accept food she could usually eat. Her eyes gets filled tears whenever the situations comes as if...she tries not use the inhaler too much as she does not want her body gets dependent on it. She is doing everything she can to heal herself. She is strong and I have faith she will become well in time.
It is hard to watch a loved one struggling with health challenges, and, thank goodness there are folks like Joe Dispenza teaching doable strategies to augment their healthcare with techniques of self connection and self care that are truly both powerful and accessible. He has a youtube channel here: ruclips.net/user/drjoedispenza as well as a website here: www.drjoedispenza.com , and there are many many beautiful testimonials here on YT which can encourage you in this work of self healing and conscious evolution, I hope you will have a peek at what is available for free, there are many interviews with Dr. Joe here on YT that can help you understand his approach, and support your partner on her healing journey. Blessings!!
Great question Michaela! After cholecystectomy, the liver continues to produce its watery version of the bile, but having removed the tissues that are expert at dehydrating that same bile, it remains water and does not have the same emulsifying power as the concentrated version, so it does not help to digest the fats as well as when the gallbladder was there. I have heard that sometimes the stub of the cut cystic duct will dilate over time post surgery and create a secondary "version" of the original gallbladder, but I am not sure that the cell lining has the same power to dehydrate as that of the original, but perhaps sometimes it might depending on how far up it was cut, I am curious about that too!
Thanks, Professor Hedley-as usual-you make this wonderful organism more comprehensive. I am really digging being a member of Integral Anatomy-dense with information, but, you patiently describe what happens 'under the hood'. Your quizzes are even informative and not just judgmental…having been in the presence of other Gross Anatomy Teachers, my sense is that you want to educate and not be a judge of those who pass or don't pass…makes learning so much easier on the Central Nervous System. Perhaps, education systems should take a look at what you are doing! Meanwhile back to the gallbaldder---Sphincter of Oddi, what's the rhythm of this valve?
Thank you Catherine! And, I'm glad you "get" my quiz strategy~ I have to have quizzes for the reckoning with the certifying organizations, so my intent is for the quizzes to reinforce rather than trick or undermine the taker!

This one is hilarious! Yesterday I was explaining it to my students learning massage the same way and took the pizza for example as well. Ahah, I really love it and your explanations are always so easy to catch. You make anatomy fantastic to learn with your amazing work! Thanks from France!
Great question! It gets "recycled!" Meaning the gallbladder is basically a "dehydrator bag," much as also is the cecum at the beginning of the large intestine, returning the water to the general circulation of the bloodstream where the heart and kidneys can "decide" what to keep and what to let go of :) Worth another video!
RIP your gallbladder Carissa~ No doubt there are fat-emulsifying supplements, though I am not at all knowledgeable about them, anyone else care to chime in on this good question??
Thanks for this, I had been wondering if the bile went in and out of the gallbladder through the same duct. I would think not, but I guess it does! Just had my gallbladder removed a few days ago (cholecystectomy) and a stone was left behind in the cystic duct stump.
I was also wondering how bile gets collected in the gallbladder.i did not get any convincing answer from text books.i got the answer through your video.Thank you.
Gil, you are freak’n hilarious!! Omg. I have almost dissected with you perhaps twice over the years before deciding I preferred living tissue vs human salad. I always pictured you as a short stocky older low key man- wow was I wrong!!! I’m going to continue watching all your videos now as you’re a gifted comedian among other things 😂
Yes Maria, it is indeed a two way street :) The enteric nervous system, local to the gut, is charged with the timing of the opening of the sphincter of oddi at the end of the common bile duct where it empties into the duodenum, cool beans!
Hi Gil! Thanks for this detailed description. Do you have any published references characterizing the vacuum pressure effect created by the gallbladder absorbing fluid from bile? Any additional information would be really helpful! I'm interested in creating a benchtop model to simulate this system and want to get as close as possible to the real deal. Thanks!
what creates the conditions for bile to back up? I have had a few times in my life when I awoke with the worst smell ( I knew it was bile) in my nose. I had to get up, walk around and thinking it was acid, drank some water with baking soda. When that didn't work, I tried lemon juice which did help. hmmm
Hmmm that is a question with many different answers! Best to consult a physician on that one if you find it occurs more than rarely, but insufficiency in your pyloric sphincter and some reflux could get you there, and these coupled with the lying down position could get matters sneaking up in the wrong direction (just thinking purely in terms of mechanics here, without consideration of physiological disturbances. See a doc if you think you need one, whether naturopath or homeopath or allopath!
Hi Ahmed! The pancreas is also producing digestive juices that flow from the pancreatic duct to the duodenum, and the bile and pancreatic juices together flow through the sphincter of Oddi into the duodenum. So they are like two rivers that together meet at a junction and then flow together. Because the gall bladder is constantly concentrating the bile by absorbing water from it, it acts as a low pressure zone relative to the pancreas when the sphincter of Oddi is closed, and so draws the fluid in its direction, rather than that of the pancreas. When the sphincter is open, the duodenum serves as a low pressure zone and draws fluid from the common bile duct and pancreatic duct. So in either case, the fluid flows away from the pancreas. Great question Ahmed, thanks for asking!
@@somanaut The gallbladder seems very important being one of the largest channels in eastern medicine and they are taken out so frequently in western medicine that would be very special information, terrific!
Hi Kerry! It's not so much excess, but rather more watery than the concentrated bile that is now missing, so the emulsifying power is not as strong per fluid unit of bile. "Where it goes" will depend somewhat on exactly how much tissue was removed. If some of the cystic duct was left, it may continue to shunt in that direction. Otherwise the common bile duct may dilate a bit to accommodate the fluid when sphincter of Oddi is closed for business!
How does bile get into the stomach, anybody know? I mean, what is happening when you have nothing in your stomach but you throw up and all that comes out is bile?
That unfortunate experience occurs when there is a reversal of flow at the pyloric valve and the bile, which enters the duodenum from the common bile duct, consequently gets up into the stomach than out the top. Memorably yucky, right?
Ohhhh I wish anatomy classes could have been this fun AND this informative. Thank you!

Do you know why having my gallbladder out -- when I drink alcohol (more than 2-3 drinks) I throw up bile for 1-2 days?
Loved this Gil…thank you.
