The Digestive System

Hello… I am a piece of cake. I was chewed by a boy and now I am put into his mouth. I am wet by his saliva. His digestive system has been doing his action.

In the mouth
I am bitten by his teeth and broken down into small pieces. His saliva from salivary glands makes me wetter. There is an enzyme in his mouth. It is ptyalin and changed me into sugar.

Here I go. I have to enter a long tube called esophagus. How can I go there? He swallowed me and squeezes me into that tube. There is a wave-like contraction that helps me to go to the stomach. It is called peristalsis. So he must not talk when he swallows me. It can make him cough.

Now I am in his stomach. His stomach is like a bag. This is a temporary store for all the food that he eats. Here, I am broken down more so I become smaller. I am mixing with the digestive juices like enzymes and acids. They make me wetter. The acid and enzymes help me break down into a thick, creamy fluid called chyme.

Small intestine
My journey is in small intestine now. The small intestine is a long tube. It is about 3.5 to 5 centimetres) around, and it's packed inside the stomach. It would be about 6.7 meters. In this place I was further broken down into smaller molecules of nutrients that can be absorbed by the villi. Villi is a tiny-finger like. Then I enter his blood vessels so my nutrients will go to his body cells. Small intestine also gets a help from the pancreas, liver, and gallbladder. I may spend as long as 4 hours in the small intestine and I will become a very thin, watery mixture.

Large intestine
I am so sad because we are not one anymore. Parts of me go to blood vessels and the other parts are useless. The useless parts have to enter the large intestine. Large intestine is wider than small intestine. Here, I get another activity. The water from was absorb, recycled and reused back to the body. The liquid paste of me changed into the solid waste. My last place now is rectum before I go out by anus.

That is my long journey.

In Singapore, I met Hansen and Arvid. Hansen and I spent our time in foodcourt and mall. We had a great holiday in Singapore. I miss to go there again.

That's my holiday.
