The<unk>  and hepatic arteries form the liver's dual blood supply. Approximately 75% of hepatic blood flow is derived from the<unk> , while the remainder is from the hepatic arteries. Unlike most<unk> s, the<unk>  does not drain into the heart. Rather, it is part of a<unk> ous system that delivers venous blood into another capillary system, the hepatic sinusoids of the liver. In carrying venous blood from the gastrointestinal tract to the liver, the<unk>  accomplishes two tasks: it supplies the liver with metabolic substrates and it ensures that substances ingested are first processed by the liver before reaching the systemic circulation. This accomplishes two things. First, possible toxins that may be ingested can be detoxified by the hepatocytes before they are released into the systemic circulation. Second, the liver is the first organ to absorb nutrients just taken in by the intestines. After draining into the liver sinusoids, blood from the liver is drained by the hepatic<unk> .
