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 largest crocodile species lives in Australia. It's the famous Australian saltwater or estuarine crocodile, known as Crocodylus porosus Males get up to 23.5 inches in length and weigh up to a ton (900 Kg or 2000 pounds). Australian females run half this weight & length. 1250 pounds is the average weight of North American crocs but it may vary depending on diet and habits of the crocodile.
