The liver receives 30% of the resting cardiac output and acts as a giant chemical processing plant in the body. These chemical reactions, called metabolism, are central in the regulation of body homeostasis.
The liver cells, called hepatocytes, contain thousands of enzymes essential to perform vital metabolic functions. They are the supermodels in the world of cellular metabolism.
The liver metabolises both beneficial and harmful substances. It stores nutrients and other useful substances, as well as detoxifying or breaking down harmful compounds. These can be then excreted from the body in bile via the liver; in urine via the kidney, or by other means.
