Passing Gas while sleeping but not releasing a bowel movement

Question

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?
