The left ventricle receives the clean blood from the left atrium and pumps it into the aorta, which is the largest artery in the body. The aorta then carries the blood to the rest of the body. Another difference between the atrium and ventricles is the valves they are attached to. Heart valves serve as a sort of seal, which open when blood is pumped from one area to the other and closes to prevent the blood from leaking backward.
The main artery going out of the right ventricle is the pulmonary artery. (Pulmonary means about lungs.) The main artery going out of the left ventricle is the aorta. The veins going into the right atrium are the superior vena cava and inferior vena cava. These bring blood from the body to the right heart. The veins going into the left atrium are the pulmonary veins. These bring blood from the lungs to the left heart. When the blood goes from the atria to the ventricles it goes through heart valves. When blood goes out of the ventricles it goes through valves.
