Cardiovascular and Respiratory System Assessment

A patient is diagnosed with left ventricular hypertrophy (thickening of the ventricle wall). Which muscular layer of the heart does this condition probably affect?

• Epicardium
• Myocardium
• Endocardium
• Pericardium

Identify the 3 primary functions of the pulmonary circuit.

• Carries blood to and from the lungs

• Pickups up oxygen

• Drops off CO2

• Carries blood to and from the body

• Drops off oxygen

Identify the 3 primary functions of the systemic circuit.

• Carries blood to and from the lungs

• Pickups up oxygen

• Picks up CO2

• Carries blood to and from the body

• Drops off oxygen

Reorder the following layers of the heart from most superficial to deep.

• Endocardium

• Parietal pericaridum

• Epicardium

• Fibrous pericardium

• Myocardium

The heart is located between the ​ (a)   . It is protected by the ​ (b)   . The heart itself has 3 layers; the ​ (c)   (outer layer), the​ (d)   (muscular middle layer), and the ​ (e)   (inner layer). Blood is pumped in two paths.

• lungs
• pericardium
• epicardium
• myocardium
• endocardium

The flow of blood from body tissues through the heart would go in the following order:

• right ventricle
• pulmonary arteries

• vena cavae
• lungs

• right atrium

The flow of blood from the lungs through the heart would go in the following order:

• aorta

• left atrium

• pulmonary veins

• body tissues

• left ventricle

The path of the heart's intrinsic conduction system is as follows:

• Purkinje fibers

• Bundle branches

• AV bundle

• SA node

• AV node

Which of the following is the best definition for stroke volume?

• The number of heartbeats per minute
• The volume of air inhaled and exhaled during normal breathing
• The amount of blood in the body
• The amount of blood pumped out by a ventricle per heart beat

Which of the following is the best definition for cardiac output?

• Amount of oxygen in the blood
• Distance blood travels in one minute

• Number of heartbeats per minute
• The amount of blood pumped by each ventricle per minute
