The names of internal medicine and surgery originated in ancient times. In ancient times, doctors could only operate on superficial diseases, while internal diseases could only be treated by non-surgical methods. So surgery is called surgery, and non-surgery is called internal medicine.

Modern surgery can be performed in any part of the body, but it is also called surgery, and its ancient name is still in use today.

In the modern sense, the medical category that still takes surgery as the main treatment means is called surgery, and the medical category that takes non-surgery as the main treatment means is called internal medicine. But its connotation has gone far beyond its original meaning. Internal medicine and surgery cannot be completely separated, and internal medicine can treat surgical diseases, and vice versa. It can be said that you have me and I have you. Some medical fields are difficult to be summarized by internal medicine or surgery, such as physical examination, blood center, pathology and so on.
