Interestingly, it has recently been demonstrated that bile acids participate in cholesterol metabolism by functioning as hormones that alter the transcription of the rate-limiting enzyme in cholesterol biosynthesis. Large amounts of bile acids are secreted into the intestine every day, but only relatively small quantities are lost from the body. Venous blood from the ileum goes straight into the portal vein, and hence through the sinusoids of the liver. Hepatocytes extract bile acids very efficiently from sinusoidal blood, and little escapes the healthy liver into systemic circulation.
Bile acids are then transported across the hepatocytes to be resecreted into canaliculi. The net effect of this enterohepatic recirculation is that each bile salt molecule is reused about 20 times, often two or three times during a single digestive phase.
It should be noted that liver disease can dramatically alter this pattern of recirculation - for instance, sick hepatocytes have decreased ability to extract bile acids from portal blood and damage to the canalicular system can result in escape of bile acids into the systemic circulation. Assay of systemic levels of bile acids is used clinically as a sensitive indicator of hepatic disease. Clinical Lipidology. How does the gallbladder work?

What's the Difference Between Indigestion and Heartburn? Was this page helpful? They break down fatty bits into a liquid form that you can digest. Your bile travels down your cystic duct into your small intestine. Then another branch of ductwork, called the pancreatic duct, joins the channel.
The pancreatic duct carries enzymes from your pancreas. Think of this as 2 rivers coming together. The digestive juices from the liver and the pancreas play a clear role in digestion.
So do other enzymes in the small intestine. The bile breaks down fat into a form the body can use. Then the enzymes from your pancreas and your small intestine get to work. If our gallbladders are removed for any reason, it can lead to a bile salt deficiency. This condition can also be caused by other diseases of the bowel.
