  3. Which chamber of the heart has the thickest wall? Explain the reason for it
    Myocardium; Because it's responsible for forcing blood out of chambers
  4. Why is the diastolic pressure considered to be clinically more important than the systolic pressure?
    Because the relaxed ventricles cause the lowest pressure in the arteries. And if the bottom # is higher than the top it causes high blood pressure
  5. Why are the capillaries the most important of the blood vessels?
