Front

What are arteries?

Back

Arteries are blood vessels that carry blood away from the heart, typically containing oxygenated blood (except for pulmonary arteries which carry deoxygenated blood).

Front

What is the function of the inferior vena cava?

Back

The inferior vena cava is a large vein that carries deoxygenated blood from the lower half of the body back to the heart.

Front

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

Back

The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae and pumps it into the right ventricle.

Front

What is the function of the aortic valve?

Back

The aortic valve regulates blood flow from the left ventricle into the aorta, preventing backflow into the heart.

Front

What does the superior vena cava do?

Back

The superior vena cava is a large vein that carries deoxygenated blood from the upper half of the body back to the heart.

Front

What is the difference between arteries and veins?

Back

Arteries carry blood away from the heart and usually contain oxygenated blood, while veins carry blood toward the heart and usually contain deoxygenated blood.

Front

What is the role of the pulmonary artery?

Back

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

Front

What is the function of the left ventricle?

Back

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

Front

What is the significance of the tricuspid valve?

Back

The tricuspid valve controls blood flow from the right atrium to the right ventricle, preventing backflow during contraction.

Front

What is the role of the left atrium?

Back

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