The flashcards below were created by user zf2010 on FreezingBlue Flashcards. What would you like to do?


  1. How is total vascular resistance changed
    Vasocontriction modulation from sympathetic NS
  2. Types of local control of blood flow
    • Basal tone - nerve independent vessel tone
    • Blood flow autoregulation - constant flow despite perfusion pressure
    • Active/Functional Hyperemia
    • Reactive Hyperemia
  3. What are the theories of autoregulation?
    Myogenic - autoregulation is intrinsic to vessel (stretched vessels contract to compensate)

    Metabolic - Vasodilator metabolites are produced by the tissue
  4. Active/Functional hyperemia
    Higher blood flow seen when functional activity increased
  5. Reactive hyperemia
    Blood flow increased after period of restricted blood flow
  6. Vasodilator metabolites
    • Adenosine
    • Hypoxia
    • CO2
  7. Vasodilator hormones
    • Bradykinin
    • Histamine
  8. Vasocontrictor hormones
    • Norepinephrine, epinephrine
    • Angiotension II
    • Vasopressin
