1. Describe the Frank-Starling law in the heart.2. Explain what happened to the pump rate when you increased the stroke volume. Why do you think this occurred? How well did the results compare with your prediction?3. Describe how the heart alters stroke volume.4. Describe the intrinsic factors that control stroke volume.1. Explain how the heart could compensate for changes in peripheral resistance.2. Which mechanism had the greatest compensatory effect? How well did the results compare with your prediction?
3. Explain what happened when the pump pressure and the beaker pressure were the same. How well did the results compare with your prediction?4. Explain whether it would be better to adjust heart rate or blood vessel diameter to achieve blood flow changes at a local level (for example, in just the digestive system).
