what chamber receives blood from lungs
The right atrium receives oxygen-depleted blood from the body through a large vein called the vena cava, then pumps it to the right ventricle below. The right ventricle receives blood from the right atrium and pumps it through the pulmonary artery to the lungs to get oxygen. The left atrium receives oxygen-rich blood from the lungs through the pulmonary veins, then pumps it to the left ventricle below. The left ventricle receives blood from the left atrium, then pumps it out through a large artery called the aorta. The aorta branches off into other, smaller arteries that carry the oxygen-rich blood to the rest of the body.
