Final answer:
Stroke volume is the volume of blood pumped from a ventricle per beat. It is an important determinant of cardiac output and is calculated by multiplying stroke volume by heart rate.
Step-by-step explanation:
Stroke volume is the volume of blood pumped from a ventricle per beat. It represents the amount of blood ejected from the heart with each contraction. Stroke volume is an important determinant of cardiac output, which is the volume of blood pumped by the heart in one minute. It is calculated by multiplying stroke volume (SV) by heart rate (HR).
For example, if the stroke volume is 80 mL and the heart rate is 70 beats per minute, the cardiac output would be 80 mL/beat × 70 beats/minute = 5600 mL/minute.
