From the right ventricle, blood is pumped into the pulmonary trunk via the pulmonic valve to the lungs. Oxygenated blood from the lungs enters the left atrium via the pulmonary veins. The left atrium pumps the blood to the left ventricle via the mitral valve. The left ventricle pumps this blood via the aortic valve to the aorta which distribute the blood to the rest of the body
