The heart, which is responsible in pumping blood into the different parts of the body, is segmented into four chambers: the left atrium, the right atrium, the left ventricle, and the right ventricle. Deoxygenated blood first enters to the right atrium before it is pumped down into the right ventricle. The deoxygenated blood from the right ventricle then enters the lungs for oxygenation. The oxygenated blood enters the left atrium, and then the left ventricle before it is pumped out of the body. The left and the right chambers are divided by a muscular wall called septum. Because fetus inside the mother’s womb gets the oxygen it needs through the placenta, there is no need for the baby’s lungs to oxygenize blood. To by-pass the lungs, the septum has natural holes that close immediately upon birth. When holes that connect the two atriums fail to close after birth, ASD occurs. There are...
