  • c

    In which chamber does deoxygenated blood return to the heart?

    a) right ventricle

    b) left ventricle

    c) right atrium

    d) left atrium

  • vena cava, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve, aorta

    List the order of blood flow.

  • open; closed

    the tricuspid & mitral valves ______ while ventricles fill; and are ____ while ventricles contract

  • closed; opened

    the pulmonary & aortic valves ______ while ventricles fill; and are _____ when ventricles contract.

  • preload

    -the ventricular stretch at the end of diastole

  • afterload

    -the pressure that the chambers of the heart must generate in order to eject blood out of the heart

  • diastole; systole

    Preload occurs during _____ while Afterload occurs during _____.

  • a

    Preload depends on

    a) ventricular filling

    b) arterial blood pressure & vascular tone

  • b

    Afterload depends on

    a) ventricular filling

    b) arterial blood pressure & vascular tone

  • venous blood pressure; rate of venous return

    What are the affecting factors of Preload? (2)

  • systemic vascular resistance; pulmonary vascular resistance

    What are the affecting factors of Afterload? (2)

  • Mean Arterial Pressure (MAP)

    -measures average pressure in the systemic circulation

    -used to assess perfusion to vital organs for patients with septic shock

  • Cardiac index (CI)

    -represents patient-specific perfusion to tissues and can be used to predict whether or not the tissue is receiving enough oxygen
