How does blood flow through the heart and body?

Deoxygenated blood from the body goes to the heart via veins. Specificially deoxygenated blood goes through the vena cava into the right atrium. Blood then moves through the atrio-ventricular valves into the right ventricle. Then the right ventricle contracts and blood goes up the semi lunar valves through the pulmonary arteries to the lungs. At the lungs, the blood becomes oxygenated. The oxygenated blood then returns to the heart via the pulmonary veins into the left atrium. Blood then goes from the left atrium into the left ventricle via the atrioventricular valves. The left ventricle contracts forcing blood up through the semi lunar valves into the aorta. The aorta distributes this oxygenated blood to the rest of the body.
