The left side of the heart then pumps the blood through the body's main artery (aorta) and out to the rest of the body. Chambers of the heart - MyHealth.Alberta.ca Then, when the right ventricle contracts, the tricuspid valve closes (to prevent blood from washing backwards into the right atrium), and the pulmonic valve opens so blood is ejected from the right ventricle and out to the pulmonary artery and the lungs, where it is replenished with oxygen. The heart is the organ that helps supply blood and oxygen to all parts of the body. An internal wall of tissue divides the right and left sides of your heart.
