When blood is traveling through the circulatory system, deoxygenated blood from the body enters the heart through the superior or inferior vena cava and empties into the right atrium. The deoxygenated blood then flows through the tricuspid valve and into the right ventricle. Once the right ventricle is filled, the blood is pumped through the pulmonary valve and into the pulmonary artery, which takes the blood to the lungs to be oxygenated. Once the blood has been oxygenated by the lungs, it returns to the heart through the pulmonary veins. This now oxygenated blood flows through the pulmonary veins and enters the left atrium, after which the blood is pushed through the bicuspid valve and into the left ventricle. Once the left ventricle is filled, the blood is pumped through the aortic valve and into the aorta, which takes the oxygenated blood to different parts of the body.
