- - - - BP pressure adjustment via radius
        
        Influence Blood flow
      - Local BP based on stretch
    - - Vasodilation: NO2 and prostacyclin
      - Vasoconstriction: endothelin and angiotensin II
    - - Increase PCO2, Low O2, Low pH :arrow_right: increase blood flow
  - - - Influences

      - Activity :arrow_right: vasoconstriction
      - Norepinephrine
        
        Alpha receptors only :arrow_right: only vasoconstriction

        High conc. :arrow_right: Alpha receptors :arrow_right: vasoconstriction
- - - - Pressor region
        
        Vasoconstriction via norepinephrine (pressor effect)
    - - Epinephrine
        
        High conc. = vasoconstriction
        
        Low conc. = vasodilation
  - - - Brain and Heart
      - Local BP (stretch)
        
        High BP -> A lot of flow -> Vasoconstriction
        
        Low BP -> Little flow -> Vasodilation
    - - Vasodilators (Prostacylcin and NO)
      - Vasoconstrictors: Endothelin
    - - Chemoreceptor activity
