Apart from the pulmonary artery and umbilical artery, all arteries carry oxygenated blood. bypass graft (CABG) surgery is a surgical procedure that involves taking a bloodA fluid that transports oxygen and other substances through the body, made up of blood cells suspended in a liquid. vessel from another part of the body, for example, the chest or the leg, and using it to bypass diseased, narrowed arteries in the heart.
