Grey’s Anatomy is the longest-running scripted series, but that doesn’t mean it’s answered all our burning questions. For example, where is Grey’s Anatomy filmed? When will the show end? And are the medical procedures accurate?

In honor of season 17, we compiled a list of questions you’ve probably asked about the popular ABC series. Keep reading for details.

1. Where is 'Grey's Anatomy' filmed?

While Grey’s Anatomy takes place in Seattle, Washington, you might be surprised to learn that it’s actually filmed in Los Angeles. Almost every location—including the E.R. and patient rooms—is built on a soundstage to ensure total control over the acoustics and lighting.

Of course, there are a few exceptions. For example, Meredith’s house is actually located in Seattle’s Queen Anne neighborhood. The cast will occasionally travel to shoot these scenes, along with other exterior shots (like the famous helipad with the Space Needle in the background).

2. How many seasons are there?

Grey’s Anatomy is currently on season 17. While most seasons consist of 24 episodes, the entire show is now streaming on Netflix (with exception of new installments, which are available for streaming on ABC).

3. When will 'Grey's Anatomy' end?

ABC hasn’t revealed when Grey’s Anatomy will air its final season. However, Pompeo previously confirmed the show’s end is near. “There is an end, and it’s nearing,” she told Us Weekly.

4. What is 'Grey's Anatomy' about?

Grey’s Anatomy follows a group of doctors working at Grey-Sloan Memorial Hospital (previously called Seattle Grace). In particular, the series focuses on Dr. Meredith Grey, whose dream is to become a famous surgeon like her mother. From family drama to fraternization among co-workers, the show offers a dramatized glimpse into the lives of doctors and soon-to-be doctors.
