Questions and Answers

Which mechanism helps counteract the effects of gravity during venous return from dependent areas?

  • Respiratory pump
  • Skeletal muscle pump (correct)
  • Valves in the arteries
  • Constriction of the veins

    • Capacitance of the venous system refers to its ability to being able to accommodate large volume of blood with only minimal change or pressure inside the vessel

    True

    What is the primary characteristic of the venous system's capacitance?

  • Its ability to pump blood to the body
  • Its ability to stretch and expand without a significant change in pressure (correct)
  • Its ability to filter waste products from the blood
  • Its ability to regulate oxygen levels in the bloodstream

    • The high capacitance of the venous system is primarily due to:
