The pulmonary veins return oxygenated blood from the lungs to which heart chamber?

Pulmonary veins deliver oxygen-rich blood from the lungs to the heart, and they empty into the left atrium. From there, blood moves through the mitral valve into the left ventricle to be pumped to the body. The right side handles deoxygenated blood (from the body to the right atrium, then to the right ventricle and onward to the lungs via the pulmonary artery). So the vessels from the lungs connect to the left atrium, not the other chambers.
