Function of liver

1) Formation of bile juice
Liver synthesized bile which help in digestion especially in fat metabolism.
Liver produce approximately 500-800ml in one day.

2) Haemopoiesis of embryo
Liver help produce red blood cells in embryo.

3) Glycogenesis 
Formation of glycogen from glucose in liver called glycogensis.

4) Gluconeogenesis
Glycogen convert into glucose in liver called Gluconeogenesis.

5) Liver helps to eliminate out the dead red blood cells from the blood.
6) Breakdown of harmful products.

7) Glycolysis take place in liver.

8) Anticoagulant factor, heparin secretes from liver.

9) Formation of urea from ammonia.
