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:
“Beside all the moral benefit which we may expect from the farmer’s profession, when a man enters it considerately, this promised the conquering of the soil, plenty, and beyond this, the adorning of the country with every advantage and ornament which labor, ingenuity, and affection for a man’s home, could suggest.”
—Ralph Waldo Emerson (1803–1882)
“A good man often appears gauche simply because he does not take advantage of the myriad mean little chances of making himself look stylish. Preferring truth to form, he is not constantly at work upon the façade of his appearance.”
—Iris Murdoch (b. 1919)
“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)
