What term describes the amount of blood pumped out of the heart with each beat?

Ejection fraction
Stroke volume
Cardiac output
Cardiac index

The correct answer is: Stroke volume

The term that describes the amount of blood pumped out of the heart with each beat is known as stroke volume. This measurement specifically quantifies the volume of blood the left ventricle ejects during one contraction. Typically measured in milliliters, stroke volume is a critical component in assessing a patient's cardiac function. While ejection fraction is related, as it indicates the percentage of blood pumped out of the heart relative to the total volume in the ventricle, it does not provide the volume itself. Cardiac output, on the other hand, refers to the total volume of blood ejected from the heart in one minute and is calculated by multiplying stroke volume by heart rate. Cardiac index is similar to cardiac output but adjusts for the individual's body surface area, giving a more personalized measure. Understanding these distinctions is essential in clinical practice, as each term reflects different aspects of cardiovascular function. Stroke volume specifically denotes the volume per heartbeat, making it the correct answer for this question.
