• mediastinum.
• epicardium.

The right atrium receives blood from the:

• vena cava.
• pulmonary veins.
• pulmonary trunk.
• aorta.

The atrioventricular valve on the side of the heart that receives blood from the inferior vena cava, is which of the following valves?

• Bicuspid
• Aortic
• Tricuspid
• Pulmonic

The pulmonary semilunar valve guards the entrance to the:

• pulmonary veins.
• pulmonary trunk.
• aorta.
• left ventricle.

The left atrium is separated from the left ventricle by the:

• bicuspid valve.
• aortic valve.
• pulmonary valve.
• None of the above.

The left atrium receives blood from the:

• superior vena cava.
• aorta.
• pulmonary veins.
• pulmonary arteries.

The primary pacemaker cells of the heart are located in the:

• SA node.
• AV node.
• wall of the left ventricle.
• left and right ventricles.

The atrioventricular node transfers the stimulation wave to the:

• SA node.
• Purkinje fibers.
• bundle of His.
• bundle branches.

The heart is roughly the size of:
