  1. Structures of the Cardiovascular System
    •Heart has four chambers and valves

    •Heart wall has three tissue layers

    •Heart muscle and tissue are specialized

    •Arteries carry blood away from the heart

    •Capillaries allow for exchange of gases

    •Veins return blood back to the heart
  2. Arteries
    • Carry blood away from the heart
    • Arterioles are smaller branches of arteries
  3. Veins
    • Carry blood toward the heart
    • Venules are smaller branches of veins
  4. Blood Vessels
    •Big: Arteries and Veins

    •Smaller: Arterioles and Venules

    •Smallest: Capillaries

    • Vasodilation- increase in the diameter of a blood
    • vessel

    • Vasoconstriction – decrease in the diameter of a blood
    • vessel
  5. Structure of the Aorta
    •Aorta moves up (ascending aorta), then arches over dorsally and runs downward (descending aorta) in front of the vertebral column

    •Aorta divides into arteries that carries oxygenated blood throughout the body
  6. Right & Left Atria
    Upper receiving chamber
  7. Right & Left Ventricles
    Lower pumping chamber
  8. Right Atrioventricular Valve
    Tricuspid valve between the right atrium and right ventricle
  9. Left Atrioventricular Valve
    Mitral valve/bicuspid valve between the left atrium and left ventricle
  10. Pulmonary Valve
    Between the right ventricle and the pulmonary artery; regulates blood flow to the lung
  11. Aortic valve
    Regulates blood flow between the left ventricle and aorta
  12. Diastole (relaxation)
    Ventricle walls relax; blood flows into the heart from the venae cavae and pulmonary veins
  13. Systole (contraction)
    Wall of the right and left ventricles contract to pump blood into the pulmonary artery & aorta
  14. Conduction System of the Heart
    •Electrical impulse originates in SA node or pacemaker of the heart

    –Blood is pumped from atria to ventricle

    • •Electricity passes to another region of the myocardium ,the AV node (atrioventricular
    • node)

    •AV node sends the excitation wave to the atriventricular bundle (or bundle of His) in the interventricular septum)

    –Bundle of His divides into left and right bundle branch

    –Ventricles contract
