The list goes on. Steroids didn't make it to baseball's banned substance list until 1991, and testing for major league players did not begin until the 2003 season, but the MLB has clearly decided that steroid use will no longer be tolerated.
The aorta (/eÉªËÉrtÉ/) 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.ne way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) diaphragm to the aortic bifurcation.
Aortic Aneurysm. The aorta is the largest artery in the body. It rises from the heart's left ventricle (the major chamber that pumps blood out of the heart) and is filled with oxygen-rich blood that travels throughout the body. The aorta itself goes from the heart, through the diaphragm, and into the abdomen. Many smaller vessels branch off from it.
