Review Sheet Results Pressure changes in the cardiovascular system primarily result from You did not answer this question. Correct answer: changes in the force of contraction of the heart. 1 What is the driving force for blood fl ow? You did not answer this question. Correct answer: pressure gradient. 2 Which of the following is directly proportional to blood fl ow? You did not answer this question. Correct answer: blood vessel radius and pressure gradient. 3 Arteries close to the heart need to be able to compensate for You did not answer this question. Correct answer: pressure changes. 4 Predict Question 1: What e ff ect do you think increasing the pressure will have on the fl uid fl ow rate? Your answer: The fl uid fl ow rate will increase. 1 Predict Question 2: Do you think a graph plotted with pressure on the X-axis and fl ow rate on the Y-axis will be linear (a straight line)? Your answer: yes. 2 This experiment uses pressure changes to model You correctly answered: changes in the force of contraction of the heart. 1 The e ff ect of increasing pressure was to You correctly answered: increase fl ow rate. 1 Blood pressure is measured in You correctly answered: mm Hg. 2 Which of the following variables has the greatest e ff ect on blood fl ow? You correctly answered: vessel radius. 3 Blood fl ow is measured in You correctly answered: ml/min. 4 Explain the e ff ect that pressure changes had on fl ow rate. How well did the results compare with your prediction? You did not answer this question. 1 How does the plot di ff er from the plots for tube radius, viscosity, and tube length? How well did the results compare with your prediction? You did not answer this question. 2 Explain why pressure changes are not the best way to control blood fl ow. You did not answer this question. 3 Use your data to calculate the increase in fl ow rate in ml/min/mm Hg. You did not answer this question. 4
