Cardiovascular Anatomy Single Best of Five Questions

Question 1 of 7

1

Angiotensin One has which one of the following effects on blood vessels?

Select one of the following:

  • Produces vasoconstriction

  • Reduces permeability

  • Increases permeability

  • Angiotensin one is an inactive precursor chemical

  • Produces vasodilatation

Explanation

Question 2 of 7

1

Papillary muscles serve which one of the following functions in the heart?

Select one of the following:

  • Direct blood flow towards the out flow tract during systole

  • Assist in keeping the lower pressured vessels patent in the heart by aposing the affect of the higher pressed atrial supply

  • Assist with expansion of the heart following systole

  • Anchor the chordae tendineae and assist in keeping the atrio ventricular valves closed during ventricular systole

  • Anchor the chordae tendineae and assist in keeping the aortic and pulmonary valves closed during ventricular systole

Explanation

Question 3 of 7

1

Which one of the following describes the components needed for effective perfusion?

Select one of the following:

  • Cardiac pump, cardiac output, heart rate

  • Cardiac pump and extra vascular muscle pump

  • Stroke volume x heart rate

  • Vascular resistance & blood volume

  • Cardiac pump, blood volume, systemic vascular resistance

Explanation

Question 4 of 7

1

With regard to the SA node, which one of following is true?

Select one of the following:

  • It is made of cardiac myocytes

  • It has automaticity at a rate of 200 beats per min

  • In health it is the only electrical connection between the atria and the ventricles

  • It is the natural pace maker of the heart

  • It is the escape pacemaker of the heart

Explanation

Question 5 of 7

1

Which one of the following coronary vessels supplies the anterior wall of the heart?

Select one of the following:

  • The circumflex

  • The left intraventrcular

  • Right coronary artery

  • Left main coronary artery

  • The coronary sinus

Explanation

Question 6 of 7

1

Which one of the following best describes the coronary ostia?

Select one of the following:

  • Is the physiological narrowing in the coronary vessel that ensures a low pressure distal to the ostia so that coronary flow is maintained

  • The coronary ostia is the opening to the right atrium off the vena cava

  • It is the opening in the aorta which supplies oxygenated blood to the coronary vessels

  • It is the point in the coronary circulation where the left coronary artery divides into the left anterior descending and the circumflex artery

  • It is the connection between the arterial and venous systems in the coronary vasculature

Explanation

Question 7 of 7

1

The aortic valve is designed to prevent flow of blood in which one of the following situations?

Select one of the following:

  • From the right atrium into the vena cava during diastole

  • The from the left ventricle into the left atrium during systole

  • From the right atrium into the vena cava during systole

  • From the aorta into the left ventricle during diastole

  • From the right ventricle into the right atrium during systole
