Answer
Birds and mammals, constantly use energy to maintain their body temperature. Therefore, they need a highly efficient supply of oxygen to the body. The mixing of oxygenated and deoxygenated blood lowers the efficiency to supply oxygen. Therefore, it is necessary to separate oxygenated and deoxygenated blood in mammals and birds.
