The disease is something that everyone should know of just as you have done telling what is SCD, because the red blood cells plays a vital role in our body I can still remember that the red blood cells delivers to working or active tissues In the lungs, hemoglobin takes on oxygen and, at the same time, releases carbon dioxide. This process is called oxygenation. At the tissue level, this activity is reversed. The same hemoglobin molecule releases oxygen and takes on carbon dioxide. This process is called deoxygenation
And we all know the importance of oxygen(respiration).
