Question

In the lab, you attach a beating heart to blood vessels and blood with different characteristics to examine resistance and blood flow in each of these situations. Your experiments are summarized in the table above.

Questions:

A. In which of the experiments in Part I do you expect the resistance to be the highest? The lowest? Explain your answer. Assume that pressure remains constant in all these experiments.

B. In which of the experiments in Part I do you expect the blood flow to be the highest? The lowest? Explain your answer. Assume that pressure remains constant in all these experiments.

C. In Part II, which of the experiments do you expect will have the greatest blood flow? Explain your answer. Assume that pressure remains constant.

D. In Part II, let’s assume that the blood flow for experiment 1 is 100 mL/min. Calculate the blood flow for experiment 3. Show your work.

E. Your friend Molly was recently diagnosed with tachycardia (i.e. an abnormally high resting heart rate) and prescribed a beta-blocker drug. Having studied the effects of agonists and antagonists for epinephrine/norepinephrine and ACh, explain to Molly how this drug will help her. How would this drug affect the force of her cardiac contractions?

Explanation / Answer

A. For the above question A in part 1 experiment 4 have high resistance and low is experiment 5 based on pressure constant in part 1 all experiment

B. For the above question B in part 1 experiment 5 have high blood flow and low is experiment 4 based on pressure constant in part 1 all experiment

C. For the above question C in part 2 experiment 2 have high blood flow and low is experiment 4 based on pressure constant in part 1 all experiment

D. if in Experiment 1 blood flow is 100ml/min then for experiment 3 it is 50ml/min
