- 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
- Elastic fibres
- High pressure spurts
- Aorta
- Leaves left ventricle
- Carries oxygenated blood to body
- Leaves left ventricle
- Pulmonary Artery
- Leaves right ventricle
- Takes deoxygenated blood to lungs
- Leaves right ventricle
- Ventricles contract and force blood out of heart and into arteries
- 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
- Narrow mesh tube
- Reduce blood flow/ clot
