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).
I am a Canuck who moved to Oz twenty years ago. My Aussie friends are used to people underestimating the size of this fine country so always make the point of how huge it is. I agree that Australia is enormous as it is a full 70% the size of Canada. That surprises THEM.
