Amanda is exercising and noticed her heart rate has nearly doubled from her resting heart rate of 68 beats per minute. Explain what effects her increased heart rate will have on cardiac output
What will be an ideal response?
Cardiac output (CO) is the product of the heart rate (HR) and the stroke volume (SV). When heart rate increases, as is the case for Amanda since she is exercising, the cardiac output will also increase. Exercise is a physical factor that leads to this increase.
