1. Which of the following terms describes the amount of blood ejected per heartbeat?

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction.

Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat.

Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
