It absolutely is a team.
You imagine them sitting around together drinking coffee, talking about how much you've peed today.
In fact, its a *relay* team.
The experts do their bit, update your records & pass on to the next expert.

The MRI people have no idea how to a biopsy & pathology people have no idea how to remove a catheter.
It's a team of experts - each doing their specialist party trick, then passing on to the next expert.
But it's a unified team with a unified goal - helping you stay out of hospital.
