a: Liver ~
b: body customs agent
What: "The liver is like the body's customs agent. Anything that enters the body via the GI tract first passes through the liver before entering the general circulation. This is called "first-pass metabolism." Circulating blood also gets a hepatic cleansing as it passes through the liver in its journey around the body."
