Final answer:
The correct calculation of stroke volume (SV) is SV = EDV - ESV, making the statement in the question false. SV is a measure of the volume of blood pumped by the heart with each beat and is key in assessing cardiac function. option b.
Step-by-step explanation:
The statement 'Stroke volume (SV) can be calculated by subtracting the end-diastolic volume (EDV) from the end-systolic volume (ESV)' is false. The correct formula for calculating SV is by subtracting the end-systolic volume (ESV) from the end-diastolic volume (EDV), not the other way around. Therefore, SV = EDV - ESV. It represents the amount of blood pumped out of the ventricle with each heartbeat.
SV is important for determining cardiac function and is used in calculations such as the ejection fraction (EF), which is the percentage of blood ejected from the heart during each contraction. SV is affected by various factors including heart size, physical condition, sex, contractility, and preload, which is the EDV.
