The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.

Oxygenated blood is the oxygen rich blood which is circulated by the aorta from the left ventricle throughout the body.

The deoxygenated blood brought by vena cava to the right atrium is pushed into right ventricle.

The right ventricle circulates it out from the heart that reaches the lungs. The lungs oxygenate that deoxygenated blood which then goes to the right atrium. The right atrium pushes the oxygenated blood into right ventricle. Then, the aorta circulates that oxygenated blood to the rest of your body .

The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.
