Front

What is the function of the left atrium in the heart?

Back

The left atrium receives oxygenated blood from the lungs via the pulmonary veins and pumps it into the left ventricle.

Front

Identify the left pulmonary vein in a diagram of the heart.

Back

The left pulmonary vein is typically labeled as 'I' in diagrams.

Front

What happens to blood after it leaves the right ventricle?

Back

After leaving the right ventricle, blood enters the pulmonary artery via the pulmonary valve to go to the lungs for oxygenation.

Front

Where is the superior vena cava located in the heart?

Back

The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the right atrium.

Front

What is the role of the pulmonary veins?

Back

The pulmonary veins carry oxygenated blood from the lungs back to the left atrium of the heart.

Front

What is the pathway of blood from the right ventricle to the lungs?

Back

Blood flows from the right ventricle into the pulmonary artery through the pulmonary valve.

Front

What is the significance of the pulmonary valve?

Back

The pulmonary valve prevents backflow of blood into the right ventricle after it has been pumped into the pulmonary artery.

Front

What type of blood does the left atrium receive?

Back

The left atrium receives oxygenated blood.

Front

What is the main function of the right atrium?

Back

The right atrium receives deoxygenated blood from the body via the superior and inferior vena cavae.

Front

What is the difference between the pulmonary artery and the pulmonary vein?

Back

The pulmonary artery carries deoxygenated blood from the heart to the lungs, while the pulmonary vein carries oxygenated blood from the lungs back to the heart.
