what do you understand by double circulation

Answer:
What is a Double 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!
Some Basic Heart Anatomy
The organ that powers the circulatory system is the heart. The human heart pumps blood through four chambers: two atria and two ventricles. We also have four valves in our hearts that keep blood moving in one direction, preventing backflow back into the heart; two valves are found within the heart itself and two are found in the major arteries in the heart: the aorta and the pulmonary artery.
Answer:
circulation in our body takes place for two purposes in two ways . one is oxygenated blood circulated from heart to various parts which is carried by arteries and veins respectively. second one is deoxygenated blood is circulated from heart to lungs which is carried by arteries and veins again but the difference here is while going to lungs pulmonary artery carries deoxygenated blood and pulmonary vein carries the pure blood.
