What is the term for the volume of blood pumped out by each ventricle during a systolic contraction?

Stroke volume (SV) (correct)

Atrial contraction volume

End-systolic volume (ESV)

End-diastolic volume (EDV)

Which wave represents the atrial contraction in the cardiac cycle?

c wave

v wave

x wave

a wave (correct)

What is the formula to calculate stroke volume (SV)?

SV = EDV - ESV (correct)

SV = EDV + ESV

SV = ESV - EDV

SV = EDV / ESV
