What is meant by double circulation? What is its significance?
The double circulation means the heart circulates or pumps the blood two times, which includes entering the blood from the body into the right auricle and ventricle from where it reaches the lung for oxygenation. Then oxygenated blood from lungs comes to the left auricle, and the ventricle reaches to all body parts.The double circulation regulated by the heart is an essential activity to ensure the quality of the blood being circulated in the body. The double circulation helps the oxygenated blood to flow in the body. It also helps the deoxygenated blood to get purified and prevents the mixing of impure and pure blood. The double circulation is a circulation of blood twice from the heart, which is important to differentiate between oxygenated and deoxygenated blood. The blood gets oxygenated through the double circulation system
