The Spinter muscle guarding the opening between Oesophagus and stomach doesnot allow the food to move in opposite direction. Even is we stand upside down, the muscle guards the opening. Rest assure the acis only produced at the time of food intake in large quantity but very little or no acid is prodeced when the stomach is empty.
