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:
“Life is a businesse, not good cheer;
Ever in warres.
The sunne still shineth there or here,
Whereas the starres
Watch an advantage to appeare.”
—George Herbert (1593–1633)
“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)
“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)
