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).
average 12 to 15 lbs. Average would be about 14 lbs. On the low end --there are 12 pounders and the highest ones are about 22 lbs. I am not exactly sure what the average one weighs I wanted a small one and the smallest I could find was 13 lbs. 12-18 lbs.
