Unknown Story

Hi! I'm Mr.elephant, and I'll be your guide as we go through the digestive system. As you can see, I first enter the mouth. Even before the delicious food enters your mouth, your salivary glands begin to produce saliva since you can already taste it. The saliva and food combinewhile you chew to form a soft food lump known as a bolus.
The bolus then passes via the oesophagus, a long, narrow tube. Our next stop is the stomach, where the bolus is forced down by the esophagus's strong walls.
Once in the stomach, hormones tell the stomach walls to release acid that breaks down the bolus into a liquid called chyme. The hormones also alert the liver, gallbladder, and pancreas to start creating bile.
From there, I enter the small intestine. The liver sends bile to the gallbladder, which holds it until I arrive. Tiny projections called villi absorb my molecules and the leftover fiber, water, and dead cells enter the large intestine.
Then, I go through the large intestine, or the colon. The colon drains out most of the fluid through the intestinal walls. This leaves a soft mass called stool.
The large intestine deposits me in a small pouch where I am held until I leave the body through the anus. And this long journey through the digestive system, which takes about 30-40 hrs, finally ends.
