Passing Gas while sleeping but not releasing a bowel movement

423 views

How does the body pass gas’s when sleeping but contain motor control to the muscles regulating bowel movements at the same time? In other words, how can we continue sleeping and pass gas, but not shart the bed?
Secondly, what mechanism makes us wake up to go the the bathroom if it’s serious enough to actually have a bowel movement (like if we were suffering from diarrhea and sick?). Same applies to urinating? How does the body know to hold it in, but when serious enough, wake us up?

People have two anuses. One internal close to the external one and the other the external one.

Gas passes by the first and the brain decides based on the situation ( visual, sleep, social) what to do with the second anus.

Gas is released without danger.
