What does increasing the pump pressure correspond to in the human heart? You correctly answered: d. increasing the force of contraction What does decreasing the right (destination) beaker correspond to in the human heart? You correctly answered: b. decreasing afterload Experiment Data: Condition Flow Rad. L Rad. R Str. V Rate Press. L Press. Dif.

11/13/17 page 3 Post-lab Quiz Results You scored 75% by answering 3 out of 4 questions correctly. 1. Which of the following compensatory mechanisms was not tested? You correctly answered: c. decreasing the pressure in the left (source) beaker 2. In an actual heart, what is the most logical way to compensate for a decrease in flow tube radius? 3. Without a difference in pressure between the pump and the destination beaker You correctly answered: a. the valve will not open. 4. Athletes experience an overall __________ in peripheral resistance, so the heart generates __________ pressure to deliver the same amount of blood. An athlete's arterial pressure would likely be __________ than that in a non-athlete. Your answer: b. increase, more, higher Correct answer: d. decrease, less, lower

11/13/17 page 4 Review Sheet Results 1. Explain how the heart could compensate for changes in peripheral resistance.Your answer: 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 resultscompare 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 locallevel (for example, in just the digestive system).Your answer:
