What is a normal value for end-diastolic volume (EDV)?

End-diastolic volume (EDV) quantifies the amount of blood present in the ventricles of the heart just before contraction. This measurement is crucial for understanding cardiac function and the heart's capacity to pump blood effectively. A normal value for EDV typically falls within the range that accommodates the variations due to factors like individual differences, physical condition, and activity levels.

In the context provided, an end-diastolic volume of 125 mL is representative of a typical value for a healthy adult's left ventricle, especially when considering physiological conditions where the volume increases slightly with activity or as a response to certain heart conditions. This volume allows for effective filling of the ventricle before it contracts, ensuring optimal ejectile performance during systole.

The other values, while not entirely outside the realm of possibility, generally do not align with typical physiological norms. Values significantly lower or higher than 125 mL may indicate specific health concerns or might reflect abnormal physiological states that deviate from standard cardiac function. Therefore, choosing 125 mL accurately reflects the expected normal range for EDV in a clinically healthy population.
