My trip, where did Douban go in the body?

I'm Xiao douban. My companions and I left the bean sprout basket, first came a pot, then a plate, and then I was picked up by a pair of chopsticks and sent to a child's mouth.

The child has two rows of neat teeth in his mouth. Many of his companions were chewed up by their teeth and their mouths were mixed with saliva. The child ate so fast that I went into the esophagus with everyone before I was chewed up.

I slid down the esophagus and came to an upside-down gourd. This gourd is the stomach. My stomach kept squirming and secreting gastric juice, and my chewing partner turned into a gruel paste. I've been in my stomach for hours, and it's still a good watercress. Later, I followed the porridge to the small intestine.

The small intestine is like a twisted tube. It secretes a lot of intestinal juice, plus bile and pancreatic juice, which mixes the paste sent by the stomach. Many nutrients in the paste are absorbed by the intestinal wall, leaving some dregs. I walked around the small intestine for a long time, but it was still a good watercress, and then I slipped into the large intestine with the dregs.

The large intestine excretes dregs. I ran out of the door along the large intestine with the scum. In this way, I walked in the child's body for nothing.
