What is the function of the pulmonary arteries?

Back

The pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Front

What is the function of the aorta?

Back

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

Front

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

Back

The left atrium receives oxygenated blood from the lungs via the pulmonary veins.

Front

What is the function of the AV node?

Back

The AV node (atrioventricular node) is responsible for transmitting electrical impulses from the atria to the ventricles, coordinating heart contractions.

Front

What type of blood is found in the left atrium?

Back

The left atrium contains oxygenated blood returning from the lungs.

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 difference between the right atrium and the right ventricle?

Back

The right atrium receives deoxygenated blood from the body, while the right ventricle pumps this blood to the lungs for oxygenation.

Front

What is the significance of the inferior vena cava?

Back

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

Front

What is the function of the left ventricle?

Back

The left ventricle pumps oxygenated blood into the aorta to be distributed throughout the body.

Front

What is the role of the heart valves?

Back

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