Actually firstly oxygenated blood comes from lungs to left atrium then atrium contracts n blood passed to left ventricle then by longest artery known as aorta, the blood goes to tissue and oxygen get used. Then the deoxygenated blood comes to right atrium through longest vein known as vana cava then it's go into right ventricle then in lungs by pulmonary artery to get oxygenated.
