The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
As the largest artery in the body, the aorta is responsible for delivering oxygen-rich blood from the heart's left ventricle through the diaphragm and into the abdomen. Branching off from the aorta is a number of smaller blood vessels responsible for blood flow to the kidneys and other digestive organs.isease is the most common cause of an enlarged aorta. Various cardiovascular conditions can cause small tears in the aorta known as dissections. When these occur near the heart, a person's life is threatened and emergency surgery is required immediately.
