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).
