      • Hepatic portal system moves nutrient and oxygen-rich blood absorbed from capillaries surrounding the small intestine/stomach/spleen/pancreas to the liver
        • Each hepatocyte, or single liver cell, contains a central vein carrying blood back to the heart
    • Detoxification of blood
      • Deaminates and synthesizes amino acids, forms urea to eliminate ammonia
    • Maintains blood glucose levels through metabolic functions (homeostasis)
      • Gluconeogenesis, Glycogenesis/Glycogenolysis, and release of glucose stores
      • Mobilizes fat and cholesterol for energy 
      • Stores and manages minerals and vitamins
