When writing for different audiences, it is important to adjust your writing. how should your writing differ if you were writing to a team of professionals versus patients?

In this case, if you are referring to medical patients (I think?) then both texts would be rather formal as they are in a professional setting. However, the language when writing to patients would, of course, include more medical jargon, while writing to a team of professionals would be serious but related to the profession. (sorry, this is my first answer, correct me if I'm wrong in my interpretation of your question?)

Don't forget your body paragraphs! and a thesis!
