  - - - Prevent back flow of blood from the lungs into the right ventricle
    - - Prevent back flow from the left ventricle into the left atrium
    - - Prevent back flow from the right ventricle into the right atrium
    - - Prevent back flow of blood from the aorta into the left ventricle
    - - muscles that assist in the strength of the valves as well as the support of the chordae tendonae.
      - May be 2-9 of these present
  - - - influenced by venous return, inotropic agents, and afterload.
    - - amount of blood that is pumped by a single ventricle (left or right) in 1 minute
    - - average blood pressure in an individual during a single cardiac cycle
    - - factor that determines the force of ventricular contraction
    - - resistance in the great arteries to the ejection of blood from the ventricles
      - involved in calculating stroke volume
    - - resistance of arteries to blood flow
