      • movement of water along concentration gradient  through semi-permeable membrane
  • Arteries narrow
    • Saturated Fats
    • Arteries
      • Ventricles contract and force blood out of heart and into arteries
        • High pressure spurts
          • Elastic fibres
            • Stretch with each spurt
          • Muscle fibres
            • Withstand high pressure of spurts
          • Folded inner lining
            • Expand as walls stretch
          • Narrow lumen
            • Maintain pressure
      • Aorta
        • Leaves left ventricle
          • Carries oxygenated blood to body
      • Pulmonary Artery
        • Leaves right ventricle
          • Takes deoxygenated blood to lungs
    • Fatty deposits under lining
      • Reduce blood flow/ clot
        • Can cause heart attack if in coronary artery
        • Cured with stent
          • Narrow mesh tube
            • Expands at narrowing pushing out walls, expanding lumen
