Explain the pathway of blood through the heart?

Deoxygenated blood spilld into the right atrium by way of the inferior and superior vena cava. The blood then funnels through the tricuspid valve and builds up in the right ventricle. With a strong contraction upward, the right ventricle pumps the blood upward through the pulmonic valve(pulmonary semilunar valve) . The blood moves through the pulmonary artery to the lungs where the exchange of carbon dioxide for oxygen takes place. Oxygenated blood then flows from the lungs into the pulmonary veins. The pulmonary veins then dumps the oxygenated blood into the left atrium. Blood funnels through the mitral valve (bicuspid valve) into the left ventricle. A powerful contraction is made to push the blood through the aortic valve(aortic semilunar valve) into the aorta where the blood is channeled throughout the body.
