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:
“The advantage of living is not measured by length, but by use; some people have lived long, and lived little; attend to it while you are in it. It lies in your will, not in the number of years, for you to have lived enough.”
—Michel de Montaigne (1533–1592)
“We must be as courteous to a man as we are to a picture, which we are willing to give the advantage of a good light.”
—Ralph Waldo Emerson (1803–1882)
“Science and art are only too often a superior kind of dope, possessing this advantage over booze and morphia: that they can be indulged in with a good conscience and with the conviction that, in the process of indulging, one is leading the “higher life.””
—Aldous Huxley (1894–1963)
