This great artery and its divisions, with their returning veins, constitute the greater, or systemic circulation.
Anyone who reads his description of the systemic circulation cannot fail to recognize that he really understood it.
The portal circulation is thus not an independent system, but forms a kind of loop on the systemic circulation.
But when Servetus comes to speak of the systemic circulation, what he has to say is as old as Galen.
It is evident that the emboli entering the systemic circulation are usually arrested in the pulmonary capillaries.
systemic circulation n.
Circulation of blood throughout the body through the arteries, capillaries, and veins, which carry oxygenated blood from the left ventricle to various tissues and return venous blood to the right atrium.
