at first, I entered a big mouth, and with the stirring of my tongue, a liquid called saliva came to me. "Crack, crack" What's that sound? Oh, it turns out that the big white machine is working. The big machine broke me into small pieces mercilessly, and then I slipped into the esophagus with saliva.
under the peristalsis of esophagus, I entered the stomach. There was a burst of acid rain, and my stomach moved at the same time. Under the rubbing of my stomach, I quickly became smaller pieces, and some protein disappeared.
I continued to drift down, past the duodenum and into the small intestine. I stepped on the hairy carpet on the inner wall of the small intestine and washed myself with various liquids in the small intestine: bile breaks down fat into fat particles, and pancreatic juice digests sugar, protein and fat ... < P > After a while of washing, I walked to the next stop-the large intestine with the peristalsis of the small intestine. There is no carpet in the large intestine, only some people who are like me but don't know each other. These people are noisy and rushing in one direction, and they seem to be very happy. I grabbed an uncle and asked, "What's the matter? What happened? " Uncle said happily, "Are you new here? Come with me, we are going out. " Before I could figure out what was going on, my uncle pulled me to squeeze up. After a period of tossing, I finally saw the sun again!
in this way, I completed this trip to the human body.
