C) Hepatic portal circulation
The hepatic portal circulation carries blood directly to the liver. If the liver has a high metabolic capacity, the drug is totally inactivated on its first pass, and no therapeutic effects occur. A drug may be given parenterally in order to avoid the first-pass effect. The liver is temporarily bypassed, and the drug reaches therapeutic levels in the systemic blood.
