Blood Pressure, Dr. D. Penney



Decreased Compliance of the Blood Vessel Wall May be Due To:

  • Wall distention, i.e. transmural pressure

  • Movement toward the arterioles in the arterial tree

  • Smooth muscle contraction, e.g. resulting from:

    - norepinephrine release from nerves

    - blood-borne epinephrine

  • Aging, e.g. increased collagen, change in collagen orientation, arteriosclerosis
