Document Summary

Chemical digestion in small intestine depending on liver, gallbladder, pancreas. Liver-largest gland in the body 4 lobes - right, left, caudate, quadrate. Liver lobules: hexagonal structural & functional unit. Made up of hepatocytes(liver cells: longitudinal central vein. Bile duct: gets bile from bile canaliculi. Portal arteriole: branch of the hepatic artery. Hepatic venule: branch of hepatic portal vein. Almost all hepatic nutrients pass by which take time. Storage of carbs(glycogen), vit a, b12, d, e, k, minerals(irons/copper) Detoxification-deactivation of: poisons, drugs, hormones from kupffer cells. Excretion of bilirubin: to the bile outside liver for rbc/hemoglobin. Phagocytosis of: from kupffer cells engulfing old/damaged cells, bacteria etc. Bile salts: cholesterol derivatives fat emulsification and absorption. Bile salts goes into duodenum ->reabsorbed into blood in ileum -> return to the liver by hepatic portal blood-> secreted from the liver as new bile. Stores/concentrates bile by absorbing water ions from it. Releases bile by cystic duct -> bile duct.
