QUIZ: Can you remember the names of these doctors who have left Grey's Anatomy?
Only the biggest Grey's Anatomy fans will be able to remember all of them.
After more than a decade on the air, it's pretty safe to say that Grey's Anatomy fans have gotten used to saying farewell to the doctors of Grey Sloan Memorial.
From Arizona Robbins to Alex Karev, Derek Sheperd to Izzie Stevens, plenty of familiar - and fan-favourite - characters have checked out over the years.
And with Alex Karev's departure set to play out in the coming weeks (Grey's have confirmed fans in North America will see how his story ends next week), we figured there was no better time to put your knowledge of the Grey's Anatomy doctors to the test.
Whether they left the hospital or are one of Grey's dearly departed, can you really remember the names of these Seattle Grace/Seattle Grace Mercy West/Grey Sloan Memorial doctors?
