What term describes the amount of blood ejected from the heart per minute?

The correct term for the amount of blood ejected from the heart per minute is cardiac output. Cardiac output is calculated by multiplying stroke volume—the amount of blood pumped by the heart with each heartbeat—by heart rate, which is the number of heartbeats per minute. Therefore, while stroke volume and heart rate are important individual components, cardiac output integrates both factors to provide a measure of the heart's efficiency in pumping blood throughout the body within a given time frame. This is crucial for understanding blood flow dynamics and ensuring that the body's tissues receive adequate oxygen and nutrients during physical activity or at rest.
