Answer:
Systemic circulation is the portion of the cardiovascular system which transports oxygenated blood away from the heart through the aorta from the left ventricle where the blood has been previously deposited from pulmonary circulation, to the rest of the body, and returns oxygen-depleted blood back to the heart.

Hii
Explanation:
pulmonary vein carries oxygen -rich blood from lungs to the left atrium. This blood is sent to left ventricle. From here it is pumped to the whole body through aorta (an artery ).Arteries divide into many small vessels called capillaries. The blood from the arteries goes to the capillaries where the nutrients Oxygen and waste material are exchanged between capillaries and tissue cells . Vena cava bring carbon dioxide rich blood from the whole body to the right Atrium . From the right Atrium blood goes to right ventricle and finally carbon dioxide rich blood pumped to the lungs through the Pulmonary artery . Heart always contains oxygen rich blood in its left side and carbon dioxide rich blood inside side .....
This is called systemic circulation.....
