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.
The liver is composed of hepatocytes that produce bile, which then passes through the bile ducts in the liver and reaches the gallbladder. The bile is stored in the gallbladder until food enters the digestive system. When foods that are high in fat reach the duodenum, the cells of the duodenum release hormones to signal to the gallbladder to release bile. This, in turn, causes the liver to produce more bile.
