  1. It indicates double circuit circulation. It includes pulmonary cir¬culation and systemic circulation.
  2. Here blood flows through the heart twice for completing one circulation. Hence it is called double circulation.
  3. In this circuit deoxygenated blood from organs of body is collected into the right auricle and then sent into right ventricle. From right ventricle blood is pumped to the lungs. In the lungs blood is oxygenated and is returned to the left auricle by pulmonary vein. This circulation is known as pulmonary circulation.
  4. In systemic circulation the oxygenated blood from the left auricle is pumped into the left ventricle. From the left ventricle blood is pumped into the systemic aorta. This aorta supplies blood to various organs of the body.
