The aorta (/eÉªËÉËrtÉ/) is the main 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.

Talk to your doctor about the best colon cancer screening schedule for your particular situation. Dec. 27, 2014 See more In-depth.
