Confidence votes 80. The left ventricular chamber of the heart is responsible for pumping blood out of your heart and through your arteries to the rest of the body. The right ventricle, receives blood returning in the veins from the rest of the body. It them sends it to be re-oxigenated in the lungs.
Each side of your heart uses an inlet valve to help move blood between the atrium and ventricle. The tricuspid valve does this between the right atrium and ventricle. The mitral valve does this between the left atrium and ventricle. The lub is the sound of the tricuspid and mitral valves closing. Each of your heart's ventricles also has an outlet valve. The right ventricle uses the pulmonary valve to help move blood into the pulmonary arteries. The left ventricle uses the aortic valve to do the same for the aorta. The DUB is the sound of the aortic and pulmonary valves closing.
