The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. The liver consumes about 20% of total body oxygen when at rest, so the total liver blood flow is quite high. Blood flow to the liver is unique in that it receives both oxygenated and partially deoxygenated blood.

The impact of obesity on health is causing increasing concern in Australia. More than one in four adults are obese, compared to one in 10 in 1989. Since the mid-1990s men are on average 3.6 kilos heavier, women are four kilos heavier, and by one estimate obesity is costing the nation $60 billion a year.
