Hey mate

Here is ur answer

The separation of oxygenated and de-oxygenated blood allows a more efficient supply of oxygen to the body cells. This efficient system of oxygen supply is very useful in warm-blooded animals such as human beings.

As we know, warm-blooded animals have to maintain a constant body temperature by cooling themselves when they are in a hotter environment and by warming their bodies when they are in a cooler environment. Hence, they require more O2 for more respiration so that they can produce more energy to maintain their body temperature. Thus, the circulatory system of humans is more efficient because of the double circulatory heart.

The blood, pumped by the heart , leaves the heart in arteries to the parts of the body and return back to the heart in veins. During this process, the blood passes through the heart twice. This is called double circulation. It is also called dual circulation.

Hope you understand now.
