Hepatic ducts: have a left and right hepatic duct that merge to form the common hepatic duct. Liver cell types: hepatocytes: most predominant cell type (comprise most of the liver). Histology of a liver lobule: liver lobule is a six sided unit (hexagon) containing hepatic (portal) triad and a central vein (functional unit of the liver) connected to others by ct. Functions of the liver (6): process intestinal nutrients (sugars, amino acids, fats, and vitamins), synthesize proteins, detoxify waste/drugs, storage of iron and excretion of bilirubin (product of heme), immune surveillance (kupffer cells), and aids in digestion (bile). Processing of amino acids: essential amino acids (only from diet, cannot make) are used for protein synthesis (e. g. albumin, fibrinogen, etc) and to make complement.
