With intrinsic regulation of the heart - the electrical impulse is generated in the:

• Atrioventricular (AV) node

• Sinoatrial (SA) node

• Perkinje Fibres

• Atrioventricular bundle (Bundle of His)

Identify the structure(s) that make up the cardiac conduction system

• Atrioventricular bundle (Bundle of Hers)

• Atrioventricular bundle (Bundle of His)

• Perkinje Fibres

• Left & Right bundle branches

Pulmonary circulation involves blood flow to the:

• Lungs

• Tissues of the Body

With pulmonary circulation, blood returning to the heart is:

• High in oxygen (oxygenated)

• Low in oxygen (deoxygenated)

• Both oxygenated & deoxygenated

• Neither oxygenated & deoxygenated

Systemic circulation involves blood flow to the:

• Lungs

• Tissues of the Body

Systemic circulation begins in the:

• Aorta

• Pulmonary artery

• Right Ventricle

• Left Ventricle

With systemic circulation, blood returning to the heart enters into the:

• Right atrium

• Left atrium

• Right Ventricle

• Left Ventricle

With systemic circulation, blood leaving the heart is:

• High in oxygen (oxygenated)

• Low in oxygen (deoxygenated)

• Both oxygenated & deoxygenated

• Neither oxygenated & deoxygenated
