Increased EDV results in decreased stroke volume, and increased stroke volume results in increased ESV.

Question

Quizplus · Accepted Answer

Increased EDV (end-diastolic volume) actually leads to an increase in stroke volume due to the Frank-Starling mechanism, where increased preload (EDV) results in greater stretch of the ventricular walls and stronger contraction. Similarly, increased stroke volume leads to a decrease in ESV (end-systolic volume) as the ventricle ejects more blood during systole, leaving less blood remaining in the chamber at the end of contraction. Therefore, the statement is false.
