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!

in the process of circulation of blood in humans blood passes twice through the heart (oxygenated form and deoxygenated form) hence it is known as double circulation of blood

in this process

oxygen rich blood comes to the left atrium... then passes to the left ventricle (all this happens due to contactions of the muscle heart) from the ventricle its passed out to all parts of the body by the aorta and the other arteries.... the blood is utilized for life processes and becomes deoxygenated.... this deoxygenated blood goes to the right atrium through the vena cava... from the right atrium blooad moves to the right ventricle... from the verntricle the deoxygenated blood is carried to the lungs by pulmonary artery... the blood is oxygenated in the lungs and this oxygenated blood goes to the heart through the pulmonary vein

 

things to note

pulmonary artery is the only artery that carries deoxygenated blood. pulmonary vein is the only vein that carries oxygenated blood

circulation from heart to pulmonary artery to lungs to pulmonary vein and back in to the heart.... this circulation can also be called as pulmonary circulation

or

The human heart has four chambers, which help deliver blood to two different circuits. ... In the pulmonary circuit, deoxygenated blood moves to the lungs where it picks up oxygen and off-loads carbon dioxide. The oxygenated blood then returns to the left side of the heart where it re-enters the systemic circuit.
