Answer 35

hepatocytes

Question 36

LIVER liver functions

Answer 36

1. bile is produced by liver for emulsifaction of fats 2. urea is produces by liver by the process of deamination 3. detoxifaction is done by the liver by destroying poisonous toxins that enter the body 4. storage of glycogen and fats 5. activation of vitamin D: 25-hydroxocholecalciferol 6. phagocytic 7. secretes insulin 8. helps in blood clotting by producing fibrinogen and prothrombine 9. digestive factors
