The circulation of blood from left ventricle to right auricle of heart via body tissues except lungs is called systemic circulation.
In this type of circulation, left ventricle contracts and pumps the oxygenated blood to aorta. Aorta gives off arteries and arterioles to all the organs of the body except lungs. From these arterioles oxygen is diffused into tissues. Finally, deoxygenated blood from the tissue is brought to right auricle by superior and inferior venacava.
