There are many hospital departments, staffed by a wide variety of healthcare professionals, with some crossover between departments.
For example, physiotherapists often work in different departments and doctors often do the same, working on a general medical ward as well as an intensive or coronary care unit.

Each department tends to be overseen by consultants in that speciality with a team of junior medical staff under them who are also interested in that speciality.
