| circulation time | The time taken for the blood to pass through a given circuit of the vascular system, e.g., the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system.
