Question

Quizplus · Accepted Answer

The volume of blood pumped out of one ventricle of the heart in a single beat or contraction is called stroke volume. Choice A (cardiac volume) is not specific enough and could refer to the total volume of blood pumped by the heart in a given time period. Choice B (input volume) is not a commonly used term in cardiology. Choice C (preload volume) refers to the amount of blood that fills the ventricle before contraction and is not the same as stroke volume.
