randomly from either one of these veins. All the deoxygented blood from parts of the body above the heart‚ comes in throught the superior vena cava into the left atrium. Then all the deoxygenated blood from parts of the body below the heart‚ comes from the inferior vena cava into the heart. Once there‚ it is pumped into the right ventricle through a flap called the tricuspid valve. From the right ventricle it goes through the pulmonary valve into the pulmonary artery. From there it goes to the lungs

the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away from the heart‚ and veins carry deoxygenated blood back to the heart. This process is called circulation. The roles are revered in pulmonary circulation. The pulmonary arteries bring deoxygenated blood to your lungs‚ while the pulmonary veins will bring
