The Cardiovascular system

The pericardium is the double sac membrane that:

• Encloses the heart

• Lines the aorta

• Makes up the heart valves

• Is found only in arteries

Blood returning to the heart from the body organs enters the:

• Left ventricle by the pulmonary artery

• Right atrium via the vena cava

• Left atrium via the aorta

• Right ventricle via the pulmonary vein

The only vein in the body to transport oxygen rich blood is :

• Aortic vein

• Hepatic portal vein

• Pulmonary vein

• Coronary vein

All arteries in the human body flow:

• To the heart

• Away from the heart

• To the lungs

• Away from the lungs

The atrioventricular valves

• Are secured to the interior of the ventricular walls with the chordae tendinea

• conduct electrical impulses

• Both have three cusps or flaps

• Are only on the right hand side of the heart.

The terms systole and diastole refer to:

• Sounds of the heart

• Rhythm of the heart

• Heart contraction and relaxation

• Rate of the heart pulse

The bundle of His

• Is found in the aorta

• Prevents backflow from the ventricles to the atria

• Is a group of arteries that supply the heart

• Is a group of Purkinje fibres

The first heart sound 'lub' corresponds to:

• Closure of the aortic valve

• Opening of the pulmonary valve

• Closure of the atrioventricular valve

• Ejection of the blood into the aorta

Blood pressure is measured by:

• Sphygmomanometer

• Stethoscope

• Electrocardiagram

• Swanson tube

• Spectrometer

The arteries that supply oxygen to the heart are:

• Coronary arteries

• Myocardial arteries

• Vena Cava

• Pericardial arteries
