Importance of double circulation.

[1] To maintain Body temperature.

[2] To separate oxygenated or deoxygenated blood.

[3] To create more pressure to pump blood round the whole body system.

Answer 2

The separation of oxygenated and deoxygenated blood allows a more efficient supply of oxygen to the body cells. Blood is circulated to the body tissues through systemic circulation and to the lungs through pulmonary circulation. It prevents the mixing of the deoxygenated and the oxygenated blood thus helps to maintain the body temperature.
