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.
(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.

HERE IS YOUR ANSWER. ......
Humans have a double circulatory system that means the blood goes through the heart twice on each complete cycle around the body. this type of system in humans is called closed system that is the blood Travels around the body inside the blood vessels.
It has two components pulmonary circulation and systemic circulation .
PULMONARY CIRCULATION - the movement of blood from heart to the lungs and back to heart constitutes pulmonary circulation .
SYSTEMIC CIRCULATION - the circulation of body from heart to different parts of the body except lungs constitutes systemic circulation .
