Advantage
Because the systemic circulation is powered by the left ventricle (which is very muscular), one advantage of this form of circulation - as opposed to open circulation, or the gill system that fish use to breathe - is that there is simultaneous high-pressure oxygenated blood delivered to all parts of the body (except for the inner epithelial lining of the lungs which receive their oxygen during the exchange of the gases themselves).

Famous quotes containing the word advantage:
“In early times every sort of advantage tends to become a military advantage; such is the best way, then, to keep it alive. But the Jewish advantage never did so; beginning in religion, contrary to a thousand analogies, it remained religious. For that we care for them; from that have issued endless consequences.”
—Walter Bagehot (1826–1877)
“I should have no objection to go over the same life from its beginning to the end: requesting only the advantage authors have, of correcting in a second edition the faults of the first.”
—Benjamin Franklin (1706–1790)
“The advantage of the emotions is that they lead us astray.”
—Oscar Wilde (1854–1900)
