double circulation in human being is neccessary because in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

Answer 2

hey buddy


Double circulation is the to and fro movement of blood from the Right Atrium to Left Atrium.

because blood should be oxyginated.
De-oxyiginated blood moves from others parts to heart and on the other hand at the same time, oxyginated blood is pumped.

This is Double-Circulation
