Answer:
Human pulmonary circulation. Oxygen-rich blood is shown in red; oxygen-depleted blood in blue.
Double circulation is the circulation of blood through heart twice while supplying the blood to the whole body. In double circulation, there are two loops or circuits where the blood travels to heart.
Systemic circulation: First stage of systemic circulation starts from left atrium to left ventricle. This transfers the oxygen rich blood to aorta for the supply to various parts of the body. Later, the veins and venules collect the blood from various parts of the body.
