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:
“Justice is simply the advantage of the stronger.”
—Thrasymachus 5th century B.C., Greek philosopher. The Presocratics, p. 259, ed. Philip Wheelwright, The Bobbs-Merrill Co., Inc. (1960)
“One great advantage which poetry has over prose—one sense in which, we might even say, it is considerably more beautiful—is that it fills up space approximately three times as rapidly.”
—James Thurber (1894–1961)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
