Question: is there a difference between surgery and operation

Answer: No, The act of performing surgery may be called a ``surgical procedure'', ``operation'', or simply ``surgery''. In this context, the verb ``operate'' means to perform surgery. The adjective ``surgical'' means pertaining to surgery; e.g. surgical instruments or surgical nurse. The patient or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of surgeon, surgeon's assistant, anesthesia provider, circulating nurse and surgical technologist. Surgery usually spans minutes to hours, but it is typically not an ongoing or periodic type of treatment. The term ``surgery'' can also refer to the place where surgery is performed, or, in British English, simply the office of a physician, dentist, or veterinarian.
