Architecture of the Circulation, Dr. D. Penney



Why not continuous arterial blood flow?

  • Need for pulsatile pressure, e.g.
    - longterm renal function
    - perfusion of major artery blood vessels
    - carotid sinus/aortic baroreceptor response

  • Turbine pump:
    - living - lack of rotating bearing in living systems
    - mechanical - possible hemolysis due to cavitation, squashing, etc.
