Questions and Answers

If the pressure at the beginning of a vessel is 100 mmHg and the pressure at the end is 80 mmHg, in which direction will the blood flow?

  • From the beginning to the end of the vessel (correct)
  • The direction of flow cannot be determined from the given information
  • From the end to the beginning of the vessel
  • The blood will not flow because the pressure gradient is zero

What is the primary factor determining the flow rate of blood through a vessel?

  • The pressure gradient between the two ends of the vessel (correct)
  • The absolute pressure within the vessel
  • The diameter of the vessel
  • The viscosity of the blood

Which of the following statements about vascular resistance is true?

  • Vascular resistance is directly proportional to the flow rate of blood
  • Vascular resistance is a measure of the opposition to blood flow through the vessel (correct)
  • Vascular resistance is independent of the friction between the blood and the vessel walls
  • Vascular resistance is higher in larger vessels compared to smaller vessels

According to Ohm's law, if the pressure gradient across a vessel increases and the resistance remains constant, what will happen to the flow rate of blood?
