Question

describe the double circulation jn human beings.why it is necessary?​

Answer 1

Answer:

Double circulation is the mechanism in which blood is passed through the heart twice in a single cycle of circulation. There are two components in double circulation- pulmonary and systematic circulation. It is necessary because the separation of oxygenated and de-oxygenated blood allows a more efficient supply of oxygen to the body cell. This efficient system of oxygen supply is very useful in warm-blooded animals such as human beings to maintain their constant body temperature.
