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:
“If what you mean by the word “matter” be only the unknown support of unknown qualities, it is no matter whether there is such a thing or no, since it no way concerns us; and I do not see the advantage there is in disputing about what we know not what, and we know not why.”
—George Berkeley (1685–1753)
“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)
“The advantage of love at first sight is that it delays a second sight.”
—Natalie Clifford Barney (1876–1972)
