What is stroke volume?
The volume of blood ejected from the ventricles with each beat
What is preload?
The volume of blood returned to the heart
What is ejection fraction (EF)?
The percentage of blood ejected from the heart under resting conditions
What is end-diastolic volume (EDV)?
The volume of blood in the ventricles at the end of diastole
What is end-systolic volume (ESV)?
The volume of blood in the ventricles at the end of systole
What is the formula for calculating stroke volume?
Stroke volume (mL) = end-diastolic volume (mL) - end-systolic volume (mL)
What is the Frank-Starling Law of the Heart?
The volume of blood ejected from the ventricles with each beat increases with an increased end-diastolic volume
What is systolic reserve volume?
The volume of blood that can still be ejected from the heart
What is diastolic reserve volume?
The volume of blood in the ventricles at the end of diastole
What is the maximum percentage of blood that the heart can eject?
50-60%
What are the three factors that determine the amount of blood ejected from the heart?
Preload, afterload, and systolic reserve volume
What is afterload?
The resistance presented to the contracting ventricle
What is stroke volume?

What is afterload?
The resistance presented to the contracting ventricle
What is stroke volume?
The volume of blood ejected from the ventricles with each beat
What are the three factors that determine the amount of blood ejected from the heart?
Preload, contractility, and afterload
What is preload?
The volume of blood returned to the heart
What is ejection fraction?
The percentage of blood ejected from the heart under resting conditions
What is EDV?
End-diastolic volume
What is ESV?
End-systolic volume
How is stroke volume calculated?
SV = EDV - ESV
What is the Frank-Starling Law of the Heart?
Increasing EDV to a point increases SV
What is diastolic reserve volume?
The volume of blood that can be added to the ventricles during diastole
What is systolic reserve volume?
The volume of blood that can be ejected from the ventricles during systole
What is the normal range of ejection fraction under resting conditions?
50-60%
What is the residual volume of blood in the heart?
The volume of blood that remains in the heart after ejection
