Arteries carry oxygenated blood away from the heart to the body (except for the pulmonary artery, which carries deoxygenated blood to the lungs).

Front

What is the significance of valves in the heart?

Back

Valves prevent the backflow of blood and ensure it flows in one direction through the heart.

Front

Front

What is the largest artery in the body?

Back

The aorta.

Front

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

Back
