the necessity of separation of oxygenated and deoxygenated because Deoxygenated blood has a lower pH (due to the carbon di oxide picked up from respiring cells as a by-product), also it has a very low concentration of oxygen. On the other hand Oxygenated blood has a neutral pH and a high concentration of oxygen.
If the two were mixed together without any separation, then our body mechanism of quickly removing acidic substances and maintaining a steady supply of oxygen throughout the body would be very very slow, if not at all efficient.
major organs such as the Brain, liver, heart and kidneys would suffer instantly if such a thing happened.
Blood separation is there not only in mammals, but every other animal. However, it is much more specialized with veins, capillaries and arteries etc. In fish, for example, this system is not as developed. They have a one-way circulation. From one major artery, oxygenated blood travels around the whole body and as it moves, the concentration of O2 and co2 are altered.
