Which chamber is labeled D?

What side of the heart is the silver probe pointing to?

• right

• left

What are the string-like structures seen in this heart?

• semilunar valves

• atrioventricular valves

• interventricular septa

• chordae tendinae

During the dissection, if you pass a probe out of the heart from the right ventricle, your probe will be leaving the heart through which vessel?

• aorta

• pulmonary trunk

• superior/inferior venae cavae

• pulmonary veins

Which chambers receive the blood as it comes back to the heart?

• ventricles

• atria

• aorta

• vena cava

How do the atrial walls compare to the ventricular walls?

• atrial walls are thicker than ventricular walls

• atrial walls are thinner than ventriclular walls

• atrial walls are red, ventriclular walls are blue

• atrial walls are bigger than ventriclular walls

What is the purpose of the heart valves?

• to allow blood to flow in only one direction through the heart

• to allow blood to flow back and forth between chambers

• to create blood pressure

• to make the lub dup sound
