Final answer:
Cardiac output is the volume of blood pumped by the left side of the heart in one minute, which is determined by multiplying heart rate and stroke volume.
Step-by-step explanation:
The volume of blood ejected from the left side of the heart in one minute is known as cardiac output. It is calculated as the product of the heart rate (the number of heartbeats per minute) and the stroke volume (the amount of blood pumped by the left ventricle with each heartbeat). The average adult's cardiac output is about 5.00 liters per minute at rest, and this quantity can significantly increase during exercise as the body's demand for oxygen rises. Stroke volume is typically in the range of 70-80 mL, and knowing both the stroke volume and heart rate, cardiac output can be easily calculated.
