How much blood is pumped by the left ventricle with each beat, known as stroke volume?

30-60 mL
60-100 mL
100-150 mL
150-200 mL

The correct answer is: 60-100 mL

Stroke volume refers to the amount of blood ejected from the left ventricle with each contraction or heartbeat. On average, the stroke volume for a healthy adult at rest typically ranges from 60 to 100 milliliters. This range is important because it indicates sufficient blood flow to meet the body's metabolic demands during rest periods. Factors such as body size, fitness level, and overall cardiovascular health can influence an individual's stroke volume, but the normative values provide a good baseline for understanding how the heart functions under average conditions. This is relevant in various scenarios, including exercise testing, cardiac health assessments, and understanding the physiological changes that occur with training. In contrast, the other ranges presented do not align with typical physiological data for stroke volume in healthy individuals. Knowing the standard stroke volume range is crucial for personal trainers and health professionals assessing cardiovascular fitness and planning exercise programs accordingly.
