Right view of heart with blood

Deoxygenated blood from the body enters the right atrium through two large veins: the superior vena cava (top) and the inferior vena cava (bottom)./nFrom the right atrium, blood passes through the tricuspid valve into the right ventricle. From there it is pushed through the pulmonary valve into the main pulmonary artery. The artery splits into left and right branches just above the left atrium, with the left pulmonary artery sending blood to the left lung and the right pulmonary artery (which snakes underneath the aortic arch and around the back of the superior vena cava) sending blood to the right lung.
