How is stroke volume calculated in the context of the cardiac cycle?

Stroke volume is calculated by dividing cardiac output by heart rate.

Stroke volume is calculated by adding end-systolic volume to end-diastolic volume.

Stroke volume is calculated by subtracting end-systolic volume from end-diastolic volume.

Stroke volume is calculated by multiplying heart rate by cardiac output.

Verified step by step guidance

Understand the concept of stroke volume: Stroke volume is the amount of blood ejected by the left ventricle of the heart in one contraction.

Identify the key components involved in calculating stroke volume: End-diastolic volume (EDV) and end-systolic volume (ESV).

Recognize the formula for stroke volume: Stroke volume is calculated by subtracting the end-systolic volume (ESV) from the end-diastolic volume (EDV).

Express the formula using MathML:

SV = EDV - ESV

Apply the formula conceptually: To find the stroke volume, measure the volume of blood in the ventricle at the end of diastole (EDV) and at the end of systole (ESV), then subtract ESV from EDV.
