Excretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.
When the liver has broken down harmful substances, they are excreted into the bile or blood. Bile by-products enter the intestine and leave the body in the faeces. Blood by-products are filtered out by the kidneys and leave the body in the form of urine. The bile produced in the liver is collected in bile canaliculi, which merge to form bile ducts. The intrahepatic ducts eventually drain into the right and left hepatic ducts, which merge to form the common hepatic duct.
