Question

With only one functional lung, it is especially important to avoid excess cardiac stress, as the heart is very oxygen dependent. Explain why a hard working heart relies on increased blood to it when its oxygen demands increase, in terms of resting state level of hemoglobin O2 unloading. Also explain the role of cardiac myoglobin, referencing pulsatile blood flow.
