Through which chambers and valves does the blood flow in the human heart?

Blood enters the heart from the body through a large vein called the Vena Cava. This blood flows freely into the right side of the heart into the right Atrium. From here the blood will pass through the Tricuspid valved, named because it has 3 leaflets. Passing through the Tricuspid valve the blood enters the right ventrical, where it is then pumped out during a heart beat into the pulmonary artery which takes the blood to the lungs where it will gather oxygen. After this the blood then flows back to the heart in the pulmonary vein into the left atrium. Following this the blood is pumped through the Mitral valve into the left ventrical, which has a thick strong muscular wall. This strong muscular wall is perfect for pumping the blood with a lot of force into the Aorta through the Aortic valve, and then to the body to provide oxygenated blood.
