Questions and Answers

Which mechanism is primarily responsible for regulating arterial pressure?

  • Slow, hormonally regulated renin-angiotensin-aldosterone mechanism
  • Microcirculation and lymph mechanism
  • Special circulations mechanism
  • Fast, neurally mediated baroreceptor mechanism (correct)

    • What is the formula for mean arterial pressure (MAP)?

  • MAP = SBP - DBP
  • MAP = HR x SV
  • MAP = CO x TPR (correct)
  • MAP = CO x RHR

    • Which control mechanisms regulate blood flow in the body?

  • Local (intrinsic) control and neural control
  • Local (intrinsic) control and hormonal (extrinsic) control (correct)
  • Neural control and hormonal control
  • Hormonal (extrinsic) control and neural control
