Front

What is the main function of the left atrium?

Back

The left atrium receives oxygenated blood from the lungs and passes it to the left ventricle.

Front

What is the role of the right atrium in the heart?

Back

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

Front

What separates the right atrium from the right ventricle?

Back

The tricuspid valve separates the right atrium from the right ventricle.

Front

What is the function of the left ventricle?

Back

The left ventricle pumps oxygenated blood to the entire body.

Front

What is the role of the pulmonary arteries?

Back

The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.

Front

What is the function of the pulmonary veins?

Back

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

Front

What is the purpose of the aortic valve?

Back

The aortic valve controls blood flow from the left ventricle into the aorta.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is delivered to the body, while deoxygenated blood is low in oxygen and returns to the heart.

Front

What is the significance of the heart valves?

Back

Heart valves ensure unidirectional blood flow through the heart chambers.

Front

What is the role of the vena cava?

Back

The vena cava returns deoxygenated blood from the body to the right atrium.
