    20.2 Blood Flow and Pressure

    • Define and use the following terms:
      • Flow
      • Resistance
      • Blood pressure
    • Explain the difference between systolic and diastolic pressure.
    • Explain pulse pressure and mean arterial pressure.
    • Looking at Figure 20.10, explain how and why blood pressure changes as it flows through the body.
    • What is the pulse? What does a change in pulse rate tell you?
    • Describe how blood pressure is measured and explain how these results relate to systole and diastole.
    • Describe how each of the following variables affects blood flow and blood pressure. Give examples of what can cause each to change:
      • Cardiac output
      • Compliance
      • Blood volume
      • Blood viscosity
      • Vessel length
      • Vessel diameter
    • Explain why veins need specific mechanisms for blood return.
    • Explain how the skeletal muscle pump returns blood to the heart.
    • Explain the differences and similarities between the skeletal muscle pump and the respiratory pump.
