I learnt some of stuff this alreadyokbile is part of the digestive system. it is made by the liver and stored in the gall bladder which releases it to E. emulsify fats or break it upFor number two none of the choices are correct. from what i learnt the large intestine absorbs the water from the digested foodI cant help much with the second part but i do know that peristalsis is the contraction action which prevent food ( chyme) from coming back up if it does you get heart burn.
