In what portion of understanding cardiac cycle physiology can the Frank-Starling Law be used for information?
a. explains how end-diastolic volume relates to stroke volume
b. explains the physiologic difference in diastolic and systolic pressures
c. helps to understand calculation of ejection fraction
d. explains the acute effects of endurance and cardiovascular training on heart health
Answer: a. explains how end-diastolic volume relates to stroke volume
The Frank-Starling Law explains how end-diastolic volume (EDV) relates to stroke volume. At rest, a normal end-diastolic volume should be approximately 125 mL.
