  • Atherosclerosis
    • Artery wall (endothelium) is damaged
      • Inflammatory response
        • Large white blood cells enter the wall from vessels
          • Cholesterol accumulates
            • A hard deposit forms called an atheroma
              • Calciumsalts and fibrous tissue accumulates
                • A hard  plaque forms
                  • wall elasticity reduces
                    • artery narrows
                      • Raising Blood Pressure
                        • Atherosclerosis
                          • positive feedback : as arteries get narrower due to the plaque, blood pressure increases- a higher chnaceof damage to artery wall=plaque=arteries narrower
