the lungsLeft atrium: one of the four chambers of the heart. The left atrium receives blood full of oxygen from the lungs and then empties the blood into the left ventricle.
Left ventricle: Receives oxygen-rich blood from the left atrium and pumps blood into the aorta.
Which of these vessels returns blood to the left atrium of the heart? The pulmonary veins transport oxygen-enriched blood from the lungs to the left atrium. The pulmonary veins transport oxygen-enriched blood from the lungs to the left atrium.
The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.
