Our heart and lungs work together to deliver oxygen and nutrient rich blood throughout the body. Oxygen and nutrient rich blood is pumped out of the heart to the body through the largest artery in the body: the aorta. In just one minute, the blood will complete its journey all the way through the circulatory system and return to the heart for more oxygen. Each heart chamber plays an important role in this process.

 The heart has four chambers. The larger, bottom chambers are called ventricles, and smaller chambers on top are called atriums. The left and right sides of the heart appear to be flipped in photos, sonograms, and diagrams, because your left atrium is on the left side of your body.

“Used” blood arrives at at right atrium through the artery known as the vena cava. The right atrium passes the blood to the right ventricle. The right ventricle then sends it to the lungs to be reoxygenated, through the pulmonary artery. Once the lungs have refilled the blood with oxygen, the pulmonary artery brings the blood back to the heart at the left atrium. The left atrium then pumps the blood to its final stop in the heart: the left ventricle. Finally, the left ventricle propels the oxygen and nutrient rich blood back into the body through the aorta.

 The left side of the heart is much stronger than the right side. The left side delivers blood to your whole body; the right side only needs to move blood to the lungs.
