So, when u/Dummlord28 asked "what are some terrifying human body facts?" we thought we'd round up some of the best answers that had us feeling a lil' uneasy:

"If you have any kind of abdominal surgery, doctors don’t arrange your bowels, they just shove them in your body and they rearrange themselves. Bowels move and contract often, you just don’t normally feel it."

"I had a 9cm ovarian cyst removed a few years ago. There was hair and teeth and tiny random bone bits in it. When the surgeon called and told me that I thought I had heard him wrong. Not teeth!? Turns out the cells in that area have the authority to create complex tissues, like hair and teeth. Gross!"
