This refers to the
liver,
gall bladder and
bile ducts, and how they work together to make
bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin. Some components are synthesised by liver cells, the rest are extracted from the blood by the liver.Bile is then secreted by the liver into small ducts that join to form the
common hepatic duct. Between meals, secreted bile is stored in the gall bladder, where 80%-90% of the water and electrolytes can be absorbed, leaving the bile acids and cholesterol. During a meal, the smooth muscles in the gallbladder wall contract, leading to the bile being secreted into the
duodenum.
