Explanation:
Two large veins called vena cava collect deoxygenated blood from the various parts of the body and pour into RA
from RA blood enters into RV.
the deoxygenated blood from RV is pumped into lungs for oxygenation by two pulmonary arteries
from the lungs oxygenated blood enter to LA and passes to LV
From LV blood is pumped to various parts of the body through aorta.
..The flow of blood twice through the heart before it is pumped through out of the body is know as Double circulation.
I hope this will be helpful.
