What do you mean by double circulation? What is its significance?
Answers
Answer:
In double circulation, blood flows twice through the heart, during each cycle of passage through the body. Double circulation is important to keep the oxygenated and deoxygenated blood separate from each other in the body and prevent their mixing. Such separation allows a highly efficient supply of oxygen to the body.
