Blood flows through the heart twice.This is called as double circulation.
Pulmonary circulation:
Deoxygenated blood from all over the body gets collected into right auricle through superior and inferior venacava and coronary sinus From there it is taken to lungs for oxygenation. through pulmonary aorta.
Systemic circulation:
Oxygenated blood from lungs get collected into left auricle through four pulmonary veins.From there it is supplied to all body parts through systemic aorta
