Blood is pumped throughout the body by the heart. It travels into the right side of the heart, out to the lungs, then back into the left side of the heart. From there, the oxygenated blood is pumped around the rest of the body.

Systemic circulation is part of the cardiovascular system where oxygenated blood is expelled from the heart and nourishes the body's internal organs and cells. Afterwards, deoxygenated blood is returned back to the heart.

Oxygenated blood pumped from heart reaches various organs of body through arteries. Arteries divide to form capillaries. Capillaries reach every cell of the body. Here exchange of oxygen, nutrients and carbon dioxide (along with metabolic wastes) takes place. The CO2 & other wastes are taken up by the capillaries. Capillaries rejoin to form veins. Veins from head & arms combine to form superior vena cava while veins from abdomen & lower portion of body combine to form inferior vena cava. the SVC & IVC open into Right Atrium of heart. It is then pumped into Right ventricle. R. ventricle pumps the blood into pulmonary artery which carries deoxygenated blood to lungs. In lungs, O2 & CO2 exchange takes place. The oxygenated blood is transported back to the heart through pulmonary veins. Pulmonary veins open into left Atrium of heart. Then it is pumped into left ventricle. L. ventricle pumps the oxygenated blood into Aorta (largest artery). Aorta further divides to form smaller arteries which transport blood to various organs of body.
