What is the normal range for stroke volume in a healthy adult heart?

30-50 ml
50-70 ml
70-90 ml
90-110 ml

The correct answer is: 50-70 ml

The normal range for stroke volume in a healthy adult heart typically falls between 50 to 70 ml. Stroke volume is a critical measure in cardiovascular physiology, representing the volume of blood pumped from the left ventricle with each heartbeat. This range reflects the heart's efficiency in supplying oxygenated blood to the body, which is essential for maintaining adequate organ function and overall health. Values higher than this range may indicate hyperdynamic circulation, which could be a sign of various conditions, while values lower than the range may suggest heart conditions or reduced cardiac output. Understanding stroke volume is crucial for evaluating cardiovascular health and making informed clinical decisions regarding patient care.
