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).
Supersize spaniel: Billy the cocker spaniel when he weighed over 23kg before his crash diet and new fitness regime gave him a new lease of life. At 23.5kg (52lbs) - and with the average weight of a healthy cocker spaniel being between six and 17kg (15 and 37lbs) - Billy had been pampered into obesity. When Jane, 68, noticed her beloved pet could no longer climb onto the sofa because of his growing bulge she enrolled him in a special pet fit club.
