Abdominal aorta, historical anatomical artwork. The abdominal cavity of this torso has been dissected to give an anterior (front) view of the aorta (orange, inverted Y- shape), the largest artery in the human body. The aorta originates from the left ventricle of the heart (not seen), descends through the thorax and diaphragm (top), and into the abdomen. Here it branches into two common iliac arteries, providing blood to the pelvis and limbs. The spinal column (white, centre) can also be seen. This illustration is taken from the 19th century French textbook The Atlas of Human Anatomy and Surgery by J. M. Bourgery and N. H. Jacob.
