_______ keep the blood flowing in the correct direction in the heart.
valves
pressure
muscle
arteries
The left side of the heart pumps the same volume of blood as the right
true
false
The major difference between the left and right ventricles relative to their role in heart function:
the LV pumps blood through the short, low-resistance pulmonary circuit
the RV pumps blood through the long, low-resistance systemic circuit
the LV pumps blood through the long, high-resistance systemic circuit
the RV pumps blood through the short, high resistance pulmonary circuit
The left ventricular wall of the heart is thicker than the right wall in order to:
accommodate a greater volume of blood
expand the thoracic cage during diastole
pump blood with greater pressure
pump blood through a shorter distance
The function of an atrium is to:
collect blood
pump blood to the lungs
pump blood into systemic circulation
pump blood to the heart muscle

left atrium
left ventricle
right atrium
right ventricle
The _____ ventricle has a greater workload than the _____.
left; right ventricle
right; left ventricle
right; systemic circulation
left; systemic circulation
Vein that empties blood from areas above the diaphragm into the right atrium
Inferior Vena Cava
Superior Vena Cava
Pulmonary Veins
Veins
