Hi! My name is Mrs. Burrito and I will be brining you along on my journey through the digestive system! First, as you see I am now entering the mouth where the saliva glands start producing saliva to help mix me into a soft clump of food called bolus.
As the bolus travels down the long tube called the esophagus, the muscular walls inside the esophagus squeezes my burrito self into the stomach which is our second destination.
Once I am inside the stomach, hormones tell the stomach to release acid and it breaks down the bolus into a liquid called chyme. Hormones also alert the liver, pancreas and galbladder to start.
From the stomach I now enter the small intestine. The liver will send some bile to the gallbladder which will hold it until I arrive. Then villi will absorb my molecules and the fiber, water and dead cells left over and I enter the large intestine.
As I go through the large intestine, I also pass through the colon. The colon drains out most of the fluids and through the intestinal walls. This then leaves a soft lump of mass called stool.
The large intestine then allows the stool that the colon has created and I am left to leave the body through the anus. This process usually takes up to 30-40 minutes.
