-Passes the tricuspid valves into the right ventricle.
-Passes through the semilunar valves into the pulmonary arteries and outside the heart to the lungs, where it gets oxygenated by gas exchange.

-Enters the heart through the pulmonary vein into the left atrium.
-Passes the bicuspid valves into the left ventricle.
-Passes through the semilunar valves into the vena aorta and gets pumped out the heart to the body.
