This is the largest artery in the body that carries blood away from the left ventricle.

This is the main artery that supplies the lungs with deoxygenated blood.

This carries oxygen-rich blood from the lungs to the heart

This is one of four valves that regulate blood flow from the upper left chamber to the lower left atrium. Has two flaps (leaflets).

This closes the lower left chamber and opens to allow blood to leave the heart.

This pumps oxygenated blood to the organs

This receives deoxygenated blood and pumps it into the right ventricle.

This pumps oxygen-depleted blood into the lungs

This is the large vein that carries blood to the right atrium from the lower and middle body

This prevents a backward flow of blood into the right atrium.

This delivers blood to other parts of the heart and acts as a vessel for blood that comes from the lungs
