Compassionate Allowance - Hypoplastic Left Heart Syndrome
The human heart is incredibly simple, yet very complex at the same time. It is simple in the fact that it is really just a large muscle; its complexity lies in the finely coordinated contractions of different parts of that muscle in order to circulate freshly oxygenated blood throughout the body, while at the same time recirculating the oxygen poor blood back to the heart and on to the lungs to receive more oxygen.
