Aorta   Listen
noun
Aorta  n.  (Anat.) The great artery which carries the blood from the heart to all parts of the body except the lungs; the main trunk of the arterial system. Note: In fishes and the early stages of all higher vertebrates the aorta divides near its origin into several branches (the aortic arches) which pass in pairs round the oesophagus and unite to form the systemic aorta. One or more pairs of these arches persist in amphibia and reptiles, but only one arch in birds and mammals, this being on the right side in the former, and on the left in the latter.

But when late syphilis gets at the base of the aorta, the great vessel by which the blood leaves the heart, and damages the valves there, the numbering of the syphilitic's days begins. Few can afford to replace much brain substance by tertiary growths and expect to maintain their front against the world. Few are so young that they can meet the handicap ...
