Why it is necessary to separate oxygenated and deoxygenated blood

Answer» If de-oxygenated blood mixes with oxygenated blood then it will flow throughout the body and will lead to death.Because all the organs of the human body needs oxygenated blood to function properly.
If oxygenated blood and deoxygenated blood are not seperated, then, the efficiency of oxygenated blood to be able to oxygenate the cells will be greately reduced and the organism like Human Being will be inefficient.
