The fatty food travels through the digestive system, getting broken down at each stage. It is first chewed in the mouth and sent down the esophagus through peristalsis. In the stomach, it is mixed with gastric juices and hydrochloric acid. It then moves to the small intestine where enzymes help with breakdown. Next, it passes through the large intestine where water and nutrients are absorbed. Finally, it reaches the rectum and is excreted from the anus.
2. Down I go Here I go, down the digestive system, I wonder what it will be like and what I will explore, the first thing I am getting entered into is the mouth of this person, she looks like she is going to enjoy me. I have many elements of me such as the patty, the bun, the lettuce, the tomato, the onion and the cheese, I wonder where all the parts of me are going to go.
3. I am now in the mouth where her teeth are mechanically breaking me down into smaller bits, and all her saliva is getting mixed with me. Mechanically getting broken
4. Down through the pipe I go Whhoooaaa now I'm going down the oesophagus which is leading down to the stomach. The way I am going down the pipe is by a process called peristalsis. Peristalsis is a wave of involuntary muscular contractions.
5. In the Stomach! I am now going to be stored in the stomach temporarily. The stomach which I am in can expand to hold between 2 and 4 litres of food. The muscle movements in the stomach wall mix me with gastric juices, which is helping break down proteins. The stomach also contains dilute hydrochloric acid, which kills germs and provides a suitable environment for protein digestion.
6. Into the 6m tube ! I have now left from the stomach and now I'm in the small intestine which is 6 metres long. After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.
7. Nearly at the end I have nearly finished my journey through the digestive system. I am now in the large intestine which is also known as the colon. The undigested part of me is now passing through the large intestine. As I am getting pushed through it by peristalsis, water , salts, vitamins are absorbed so that they can be reused by the body.
8. Into the rectum, I go! I am now at the final part of myself getting digested. I have just come from the large intestine and now I am in the rectum. The rectum is the final part of the large intestine and it is where the faeces are stored. Time has now passed and it’s time to come out of the anus I go into the AHHHHHH TOILET!
