I am a white bread I am but inside my fellow human and chewed in the mouth and breaks down my carbohydrates and then I become a boules then I am swallowed through the esophagus which pushes me to the stomach which then I digest into chyme and then the stomach secrets it’s juices to break down the protein then I’m pushed to the small intestine dejunume where liver secretes bile to gallbladder then gallbladder secretes it and stores it. Also the pancreas secretes also enzymes to break it down. Then intestine justices break me down then I am sucked up of my nutrients and put into cells and then my remains go to large intestine where water and minerals are absorbed and then I’m sent to the rectum then anus to land in a toilet water to take on a new journey. :) hope this helps so how
