Final answer:
The volume of blood pumped per heart beat compared to the maximum filling of the ventricle is called the stroke volume. (Option b)
Step-by-step explanation:
The volume of blood pumped per heart beat compared to the maximum filling of the ventricle is called stroke volume. It is calculated by subtracting the end-systolic volume from the end-diastolic volume. Stroke volume is used to calculate the ejection fraction.
Stroke volume refers to the amount of blood ejected from the ventricle during each contraction. It is calculated by subtracting the end-systolic volume (ESV) from the end-diastolic volume (EDV).
Stroke volume is an important measure of the heart's efficiency and is used to calculate the ejection fraction, which represents the percentage of blood pumped out of the heart with each contraction.
Therefore, the correct option is: b) stroke volume
