  1. What are the layers of the pericardium starting from the outside?
    • Fibrous Pericardium
    • Parietal Serous Pericardium
    • Paricardial Cavity filled with serous fluid
    • Visceral Serous Paricardium
  2. What are the wall layers starting from the outside?
    • Epicardium = visceral layer of pericardium
    • Myocardium (muscle layer)
    • Endocardium
  3. What are the 4 chambers of the heart?
    • Right Atrium
    • Left Atrium
    • Right Ventricle
    • Left Ventricle
  4. What are the 2 valve groups in the heart and what are the 4 valves?
    • Atrioventricular Valves - Tricuspid valve, Bicuspid valve
    • Semilunar Valves - Pulmonary semilunar, Aortic sumilunar
  5. Trace the path of electricity conduction in the heart.
    • Sinatrial pacemaker node
    • Atrioventricular valves
    • Purkimjy Fibers (L/R)
    • Papillary Muscle
  6. Assign each term to its respective side of the heart.
    Less developed muscle
    Pumps blood
    Collects Blood
    Well developed muscle
    Right - passive, less developed muscle, collects blood

    Left - active, well developed muscle, pumps blood
  7. What are the properties of arteries and veins?
    Arteries - elastic, high pressure

    Veins - inelastic, low pressure
  8. Trace a blood cell through the cardiovascular system, starting with systemic circulation.
    • Systemic Circulation
    • Superior/Inferior Vena Cava
    • R. Atrium
    • Tricuspid Valve
    • R. Ventricle
    • Pulmonary Semilunar Valve
    • Pulmonary Artery
    • Lungs
    • Pulmonary Veins
    • L. Atrium
    • Bicuspid Valve
    • L. Ventricle
    • Aortic Semilunar Valve
    • Aorta
    • Systemic Circulation
  9. What is Poiseulle's Eqn?
    Image Upload 1
  10. Why is vessel radius a more important factor in controlling blood flow than vessel length?
    Once growth ceases, length does not change.
  11. What is diastole?
    Ventricles relaxed
  12. What is systole?
    Ventricles contract
  13. What is cardiac output?
    Amount of blood each ventricle pumps per minute
  14. What is Starling's Law?
    When the rate at which blood returns to the heart changes, the heart will adjust its output to match the change in inflow.

    Change in inflow = change in outflow
  15. What is stroke volume?
    Amount of blood pumped to the body per contraction per ventricle
