Key Points

  • The liver is the largest Exocrine gland in the body.
  • It weighs about 1.5 kg.
  • It is situated on the right side of the body.
  • Many toxic waste products as well as excretory products are produced in the liver.
  • It also produces proteins like Prothrombin and Fibrinogen and Vitamins like A, D, K and B12.
  • Heparin, Urea and Bile Juice are produced in the liver.
  • The liver is only present in Vertebrate animals.
  • Iron is stored in the liver in the form of 'Ferritin' while glucose is stored in the form of "Glycogen".
  • "Kupffer cells' work as a scavenger for micro-organisms in the liver and also helps in eliminating toxic substances.
  • Waste products such as Urea, Uric Acid, Creatine and Bilirubin are produced in the liver.
  • Many factors such as Bile Juice, fatty acids cholesterol, phospholipids and also 50% of lymph in the body are produced by the Liver only.
  • Most of the metabolic processes in the body such as Glycogenesis (conversion of Glucose to Glycogen), Glycogenolysis(conversion of Glycogen to Glucose), Gluconeogenesis(formation of Glucose from noncarbohydrate substance), Deamination(conversion of ammonia to Urea) are carried out in the liver, that's why liver is considered as 'Busy Organ'.
  • The liver is supplied by both oxygenated as well as deoxygenated blood.
  • Rate of blood supply to the liver is 1500ml/min.(1000ml deoxygenated +500ml oxygenated).
  • Artery providing blood supply to the liver is known as Hepatic artery.
  • The major supply of blood to the liver is by 'portal vein'(75%) & remaining (25%) by Hepatic artery. That is why the liver is known to have 'Dual blood supply'.
  • Maximum blood is stored in 'liver' in human being while in frogs it is stored maximally in 'Spleen'.
