Does removal of any certain ancillary organ cause a person to die? Obviously we need brain, heart, lungs, etc but what about the rest? Obviously people with removed pineal glands are still alive, but has any other gland like that caused people to die every time?
but that'd mean you just couldn't produce a necessary chemical for your body to function. I'm wondering more along the lines lets say if everyone would die if they didn't have a pineal gland. any other gland in the body that you'd die without?
