    Study Notes

    Liver Functions

    • The primary function of the liver is to filter blood, detoxify, and perform various metabolic processes.

    Liver Viability

    • A minimum of 25% functioning liver tissue is required to sustain life.

    Bile Composition

    • Bile is composed of water, bile salts, cholesterol, and bilirubin.

    Vitamin K and Liver Function

    • Vitamin K is necessary for the liver to synthesize prothrombin and other clotting factors.

    Enterohepatic Circulation of Bile

    • The primary function of the enterohepatic circulation of bile is to recycle bile salts and fat-soluble vitamins.

    Ammonia in the Liver

    • During gluconeogenesis, ammonia is produced in the liver and converted into urea for excretion.

    Glucose Supply to the Liver

    • The hepatic artery supplies glucose to the liver for storage as glycogen.

    Liver and Fat Metabolism

    • The primary role of the liver in fat metabolism is to regulate lipid synthesis and breakdown.

    Function of Albumin

    • The primary function of albumin synthesized by the liver is to maintain plasma oncotic pressure and transport fatty acids.

    Hepatocyte Function

    • The main function of hepatocytes in the liver is to perform various metabolic processes, including detoxification, synthesis, and storage.

    Vitamin D3 in the Liver

    • In the liver, 25 OH D3 is converted into calcitriol, the active form of vitamin D.
