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.
Mini-Aussie Ideal Weight. I have a 3 year old female Miniature Aussie and she currently weighs 30 pounds. She gets moderate exercise (2 mile brisk walk each morning; chasing rabbits, birds, etc around a 1 acre yard).
The koala is about 60 to 85 cm (24 to 33 inches) long and weighs up to 14 kg (31 pounds) in the southern part of its range (Victoria) but only about half that in subtropical Queensland to the north. Virtually tailless, the body is stout and gray, with a pale yellow or cream-coloured chest and mottling on the rump.
