Hi, I'm Oliver the Orange. And after I'm eaten...
...parts of me end up here. But how did I get here?
First I start in the mouth, where I'm mixed up with saliva to get chemical digestion started.
Then I go down the esophagus to the stomach. In there, I become partially digested by my acid friends, turning me into chyme. At the same time, digestive juices like bile from the liver and gallbladder, and enzymes from the pancreas are sent down to digest me more.
From the stomach, I go to the small intestine where my nutrients are absorbed. When contractions move me through the intestine, it's called peristalsis.
From the small intestine, I move to the large intestine, where water is absorbed. The last section of the large intestine is the rectum, where I'm compressed until I'm removed through the anus.
That's the story of my journey through the digestive system and how I end up here.
