Experiment ResultsPredict Question:Predict Question: If the pump rate is analogous to the heart rate, what do you think will happen to the rate when youincrease the stroke volume?
Stop & Think Questions:
Why did changing the ending pump volume (ESV) automatically change the stroke volume?
How does the heart provide for an increase in stroke volume?
