You have two "popliteal fossa" in your body. What couldn't you do if you didn't have them?

If you look at someone's legs from behind, you can spot the "popliteal fossa," which you might refer to as the "knee pits". It's the hollow area behind the knees that allow them to bend, and where blood vessels and nerves pass relatively superficially.
