Answer:
Here is ur answer dear...
DOUBLE CIRCULATION: The deoxygenated blood is collected into the right atrium by inferior and superior vena cava.Then it passes down to right ventricle.
When the right ventricle contracts,it goes to the lungs.
After oxygenation from the lungs it comes to left atrium and then to left ventricle.
Oxygenated blood from left ventricle is supplied to all other body parts.
So the same blood passes through the heart twice, once as deoxygenated and other time as oxygenated, this is known as double circulation.
