Part 1-The Heart (Structure)

Front

What is the valve that blood is forced through from the right ventricle into the pulmonary arteries?

Back

Pulmonary semi-lunar valve.

Front

What is the name of the valve that separates the right atrium from the right ventricle?

Back

Tricuspid valve.

Front

When the ventricles contract, which valve prevents blood from flowing from the left ventricle to the left atrium?

Back

Bicuspid (mitral) valve.

Front

Where is the tricuspid valve located?

Back

Between the right atrium and right ventricle.

Front

What are the valves between the atria and ventricles known as?

Back

Atrioventricular valves.

Front

What is the function of the pulmonary semi-lunar valve?

Back

To prevent backflow of blood into the right ventricle after it has been pumped into the pulmonary arteries.

Front

What is the role of the tricuspid valve during the cardiac cycle?

Back

It opens to allow blood to flow from the right atrium to the right ventricle and closes to prevent backflow.

Front

What is the difference between atrioventricular valves and semilunar valves?

Back

Atrioventricular valves are located between the atria and ventricles, while semilunar valves are located between the ventricles and the arteries.

Front

What happens to the mitral valve during ventricular contraction?

Back

It closes to prevent blood from flowing back into the left atrium.

Front

What is the significance of the aortic valve?

Back

It regulates blood flow from the left ventricle into the aorta.
