Sort this according to the order in which oxygenated blood from the lungs travels to other parts of the body.

• E. Lungs

Answer 1

The oxygenated blood from the lungs is brought back to the heart through the pulmonary vein. The blood enters the left atrium and then moves to the left ventricle. Then the blood from the left ventricle is pumped into the aorta. The aorta transports this oxygenated blood to all parts of the body.
