.... circulation in addition to the pulmonary and systematic circulations described above, a subsidery to the venous system exists, known as portal circulation.

.... life is by all practical means over. There is no reason to keep them alive. The only way to end their physical life is by euthanasia.

.... there is the recognition that vitamins play a role in preventing disease and maintaining health. Vitamins do not contain calories and do not supply energy. In other words, they do not contribute to weight gain. They are, however, most important as constituents of enzymes, those organic catalysts which enable biological processes to take place. It is totally impossible to imagine life without vitamins and enzymes. Through enzymes, vitamins stimulate metabolic processes, converting food to energy and accelerating biological functions. They are truly vit .....
