The ultimate objects of scientific medicine are to prolong human life and to alleviate suffering. The two great branches of the healing art - Medicine and Surgery - are so intimately related that it is impossible to draw a hard-and-fast line between them. Surgery may be defined as "the art of treating lesions and malformations of the human body by manual operations, mediate and immediate." The origin of the word surgery comes from the Greek word "cheirourgikē" (cheir hand, ergein work).
