4. Blood enriched with oxygen moves from the lungs to the left atrium through the pulmonary veins and then enters the left ventricle. 5. This blood is then ejected into the aorta, the first artery of the systemic circulation, and is distributed to all parts of your body.rom the lung blood comes through pulmonary veins to the section of the heart called the left atrium. The left atrium pumps to the left ventricle. The left ventricle pumps out through aorta to the rest of the body to deliver the oxygen. Once delivered, it returns to the right atrium to begin the cycle once more.
After the blood receives oxygen, it returns to the left side of the heart, the left atrium. After collecting in the left atrium, it is pumped into the left ventricle, and from there it is pumped into the aorta, the largest blood vessel in the body. From the aorta, blood courses throughout the body through its arteries. For blood to go in only one direction, forward, it must pass through the heart valves, which function as one-way doors, opening and shutting with each beat of the heart. Just as there are four chambers to the heart, there are four heart valves.
