Yes. For example:The black widow causes pain, and may kill you with its bite.When a woman is giving birth, the pain may be too much to bare and die.

i dont really know but i think that it is because you have a heart in every part of your body and whenever it gets hurt you can feel it
When you are angry you yell, when you are sad you cry, when you are happy you laugh, moaning is just a natural reaction the body has to pain.
