From ancient times to modern day, medicine has changed in leaps and bounds. Many discoveries have been made through trial and error. Vaccines, organ transplants, blood transfusions, and pacemakers are just a few of the things medical advancement has brought us. However, at the root of all of this, there are the theories that we base our medical knowledge on. These theories, the humoral concept of disease, the anatomical theory of disease, and germ theory are what has lead us to modern medicine, and changed not only how we see and treat disease, but also the human body.
