Pulmonary veins carry the oxygenated blood from the lungs to the hearts left atrium (upper heart chamber). The process of circulation includes the intake of metabolic materials, the conveyance of these materials throughout the organism, and the return of harmful by-products to the environment. While the heart is the largest "organ" of the circulatory system, it is really only a large blood vessel surrounded by muscles. Red blood cells, also called erythrocytes, make up about 40 to 45 percent of the bloods volume. When atrial pressure is greater than ventricular pressure, the AV valves open.
