Physiology: Review of Circulation
The right atrium receives deoxygenated blood from the body via the superior and inferior vena cavae. The deoxygenated blood from right atrium flows through the tricuspid valve into the right ventricle. From the right ventricle, the deoxygenated blood is pumped through the pulmonic valve into the pulmonary artery and out to the lungs. After being oxygenated in the lungs, the blood is sent through the pulmonary veins into the left atrium. This oxygen-rich blood then flows from the left atrium through the mitral valve and into the left ventricle. It is then pumped through the aortic valve into the aorta and out to the peripheral circulation. Finally, blood is returned from the peripheral circulation to the right atrium, and the cycle continues.
