Who is Who?
The hospital is its very own ecosystem, filled with unique species that all do differnet things. For example, you have attendings who make the decisions, you have the interns who are learning how to identify a health problem, you have x-ray techs who discover things that are hard to find, and you have nurses who will do everything they can to help you make it through this hard time. It is complicated but once you get an idea of how it works you understand why it is this way.
