What is the function of the pulmonary vein?

Back

The pulmonary vein carries oxygen-rich blood from the lungs to the left atrium of the heart.

Front

What does the left ventricle do?

Back

The left ventricle pumps oxygenated blood into the aorta, distributing it to the rest of the body.

Front

Which chamber of the heart receives oxygenated blood from the pulmonary veins?

Back

The left atrium receives oxygenated blood from the pulmonary veins.

Front

What is the role of the tricuspid valve?

Back

The tricuspid valve prevents the backflow of blood from the right ventricle into the right atrium.

Front

Which blood vessel carries deoxygenated blood from the right ventricle?

Back

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.

Front

What is the main function of the aorta?

Back

The aorta is the main artery that carries oxygenated blood from the left ventricle to the body.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the body, while deoxygenated blood is low in oxygen and is carried from the body to the lungs.

Front

What is the role of the right atrium?

Back

The right atrium receives deoxygenated blood from the body through the vena cava.

Front

What is the function of the pulmonary valve?

Back

The pulmonary valve prevents backflow of blood from the pulmonary artery into the right ventricle.

Front

What is the significance of heart valves?

Back

Heart valves ensure unidirectional blood flow through the heart chambers, preventing backflow.
