Starting from the right atrium, blood flows through the tricuspid valve into the right ventricle, then through the pulmonary valve into the pulmonary artery and lungs. After oxygenation, blood returns to the left atrium, passes through the mitral valve into the left ventricle, and finally through the aortic valve into the aorta for systemic circulation.
