The<unk>  or hepatic<unk>  (HPV) is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood contains nutrients and toxins extracted from digested contents. Approximately 75% of total liver blood flow is through the<unk> , with the remainder coming from the hepatic artery proper. The blood leaves the liver to the heart in the hepatic<unk> s. The<unk>  is not a true<unk> , because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic<unk>  system, one of only two<unk> ous systems in the body – with the hypophyseal<unk>  system being the other. The<unk>  is usually formed by the confluence of the superior mesenteric, splenic<unk> s, inferior mesenteric, left, right gastric<unk> s and the pancreatic<unk> . Conditions involving the<unk>  cause considerable illness and death. An important example of such a condition is elevated blood pressure in the<unk> . This condition, called<unk>  hypertension, is a major complication of cirrhosis. In abdominal obesity fats, inflammatory cytokines and other toxic substances are transported by the<unk>  from visceral fat into the liver, leading to hepatic insulin resistance and non-alcoholic fatty liver disease.
