Bile and Its Functions
  • The liver makes 800 ml to 1200 ml of bile per day.
  • Its pH is 8.6 in liver and 7.6 in the gallbladder.
  • It is golden yellow or green in colour.
  • It is a mixture of water, bile salts, bile pigments, phospholipids (such as lecithin), electrolytes, cholesterol, and triglycerides.
  • It is released into the duodenum when stimulated by cholecystokinin (CCK).
  • The bile salts are as follows:
    • Sodium glycocholate
    • Sodium taurocholate
    • Potassium glycolate
    • Potassium taurocholate
  • Bile salts act as emulsifying agents, so they are also important for the absorption of digested lipids.
  • The bile pigments are formed by the degradation of the haemoglobin.
  • Bilirubin and biliverdin are the main bile pigments.
