Answer:-
In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.
The double circulation of blood includes:
(i) Systematic Circulation
(ii) Pulmonary Circulation
Systematic Circulation: It supplies oxygenated blood from left auricle to left ventricle, thereby pumped to various body parts. The deoxygenated blood is collected from the various body organs by the veins to pour into vena cava and finally into the right atrium (auricle). Right atrium transfers the blood into the right ventricle.
Pulmonary Circulation: The deoxygenated blood is pumped by the right ventricle into the lungs for oxygenation. The oxygenated blood is brought back to left atrium (auricle) of the human heart. From left atrium, the oxygenated blood is pushed into the left ventricle. The left ventricle pumps oxygenated blood into aorta for systematic circulation.
Necessity (Importance) of Double Circulation:
There is a partition between the right side and the left side of human heart which is particularly useful to prevent mixing of deoxygenated with oxygenated blood. This type of separation of deoxygenated and oxygenated blood ensures highly efficient supply of oxygen to the body. This is important in case of humans because it constantly gives energy to maintain their body temperature.

Hey dear.....
Here is ur ans....
Circulation System?
The majority of mammals (including humans) utilize a double circulatory system. This means we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.
Double circulatory systems are important because they ensure that we are giving our tissues and muscles blood full of oxygen, instead of a mixture of oxygenated and deoxygenated blood. While it may take a bit more energy than a single circulatory system, this system is much more efficient
Why it is necessary...??
Double circulation is necessary to mainatian the Difference between oxygenated and deoxygenated blood in our body...and also to make body work efficiently and main tane it's body temp...
How It hlps u dear...
Have a good day dear...!!
