     True
     False
  • 8
    - The right heart is filled during the diastole, the left heart during the time between the
    diastole and systole
     True
     False
  • 9
    - A typical value for systolic blood pressure within the right ventricle is about 4.6 kPa
     True
     False

    within the ventricles
     True
     False
  • 11
    - Typical values of systolic blood pressure within the left ventricle (and in the aorta) are
    about 16 mm Hg (16 torr)
     True
     False
  • 12
    - 1 kPa is approx. 7.5 torr (mm Hg), and this equals to approx. 10 cm H2O
     True
     False
  • 13
    - The model of vessel elasticity illustrates the important role, which the elasticity of aorta and arteries plays for an appearance of diastolic blood pressure
     True
     False
  • 14
    - The model of blood vessels elasticity shows a lower volume of liquid being flowed within the elastic pipes comparing the rigid (glass) pipes
     True
     False
  • 15
    - The wall of right ventricle is about three fold thicker than the wall of left ventricle
     True
     False
  • 16
    - The heart in healthy adults pumps approx. 5 liters of blood at rest throughout the system circulation (large blood circuit)
     True
     False
  • 17
    - The blood flow through the pulmonary circulation (small circuit) is lower than the flow
    through systemic circulation (large circuit)
     True
     False
  • 18
    - The higher is a blood pressure and the larger is the diameter of blood vessel, the higher is the mechanical tension within the walls of blood vessels (Laplace law)
     True
     False
  • 19
    - A mean blood pressure can be calculated as the value of diastolic pressure plus one third of the pulse pressure (pressure amplitude)
     True
     False
  • 20
    - A mean blood pressure is higher than the arithmetic average of systolic and diastolic
    pressure - a contraction of a heart myocardium requires instant increase of potassium concentration within the sarcoplasm
     True
     False

    measurement
     True

     True
     False
  • 23
    - A transducer (detecting „head gauge“) for a measurement of blood pressure can employ the changes of resistance, capacity, or inductance (resistive-tensometric, capacitive, or inductive transducing)
     True
     False
  • 24
    - Using a palpate method we can determine the mean arterial blood pressure
