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:
“A regular council was held with the Indians, who had come in on their ponies, and speeches were made on both sides through an interpreter, quite in the described mode,—the Indians, as usual, having the advantage in point of truth and earnestness, and therefore of eloquence. The most prominent chief was named Little Crow. They were quite dissatisfied with the white man’s treatment of them, and probably have reason to be so.”
—Henry David Thoreau (1817–1862)
“It’s a great advantage not to drink among hard-drinking people. You can hold your tongue and, moreover, you can time any little irregularity of your own so that everybody else is so blind that they don’t see or care.”
—F. Scott Fitzgerald (1896–1940)
“The advantage of time and place in all practical actions is half a victory; which being lost is irrecoverable.”
—Francis, Sir Drake (1540–1596)
