The liver is crisscrossed with a densely packed web of blood vessels and special pathways called bile ducts. Liver cells are called hepatocytes. The blood enters through the portal vein and the hepatic artery. It leaves by way of the hepatic vein. Tucked beneath the liver towards the right side is a pear-shaped organ called the gall bladder, whose main function is to store and concentrate bile. The gall bladder is connected to the liver by way of biles ducts. Bile is collected in the liver bile ducts and transported to the gallbladder, where it is concentrated and stored .

Secretion of Bile and the Role of Bile Acids In Digestion

Bile salts are reabsorbed by the last portion of the small intestine, extracted by the liver, and resecreted into bile. This recirculation of bile salts is known as the enterohepatic (Of or involving the intestine and liver.) circulation.    Enterohepatic recirculation is the process by which a drug is reabsorbed in the gastrointestinal track (GIT) after biliary excretion.

Bilirubin (the main pigment in bile) is excreted in bile as a waste product of destroyed red blood cells, giving stool a green-brown color. SOURCE = RBC

Drugs and other waste products are excreted in bile and later eliminated from the body.

bilirubin

Bilirubin is the waste product that results from the breakdown of hemoglobin molecules from worn out red blood cells. Ordinarily, it is excreted from the body as the chief component of bile. Excessive levels of bilirubin stain the fatty tissues in the skin yellow; this condition is called jaundice. Very high levels of bilirubin in the bloodstream can cause permanent damage to certain areas of the brain of newborn infants - kernicterus. This can cause a characteristic form of crippling known as athetoid cerebral palsy. To prevent this from happening, bilirubin levels are monitored in newborns, and excessive levels of bilirubin are treated by either phototherapy ("bilirubin lights") or exchange transfusion.

Bilirubin  is the main bile pigment that is formed from the breakdown of heme in red blood cells.  The presence of drugs that interfere with glucuronyl transferase impairs the liver's ability to conjugate bilirubin - inability to conjugate bilirubin results in high circulating levels of unconjugated bilirubin, which, if untreated, passes through the blood-brain barrier and can produce encephalopathy.
 

bile - Definition of bile by Webster's Online Dictionary - a yellowish green fluid made by the liver from bile salts, bilirubin (broken down red blood cells), cholesterol, and other substances; the fluid stored in the gallbladder; the fluid released from the gallbladder into the intestine to help fat digestion

Another problem that can arise is the loss of bacteria that the intestines need. These good bacteria may be wiped out when antibiotics are used.

Bilirubin is a breakdown product of hemoglobin.

The inability to conjugate bilirubin results in high circulating levels of unconjugated bilirubin, which, if untreated, passes through the -brain barrier and can produce encephalopathy. bile
