Answer
From the right atrium it passes through the tricuspid valve into the right ventricle, then through the pulmonary artery to the lungs, where it is oxygenated. It returns by the pulmonary veins to the left atrium, passes through the bicuspid valve into the left ventricle and is pumped through the aorta to the body, returning by the venae cavae to the right atrium.
