The systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.The system of blood vessels in the human body measure about 60,000 miles (96,560 kilometers).Arteries carry oxygen-rich blood from the heart through the body. Veins carry oxygen-poor blood back to the heart. The superior vena cava carries oxygen-poor blood into the heart.The aorta carries oxygenated blood from the heart to organs and tissues.

The Circulatory System. Veins, arteries and capillaries are the three types of blood vessels in the circulatory system. The blood vessels carry blood, which contains antibodies, nutrients, oxygen, electrolytes and hormones, throughout the body to be used by the organs.xygen rich blood is pumped out of the left ventricle of the heart into the aorta, which is the largest artery in the body. The oxygen rich blood travels through the aorta into smaller arteries. The capillaries sit between the arteries and the veins, connecting the two together and acting as an exchange stop.
