By this stage I have become tiny particles that is being absorbed by blood. The inner lining of the small intestine is covered by tiny cactus like projection called villi, it increases the surface area to allow more nutrients to be absorbed by the walls of the intestines so they can enter the blood and be transported around the body, did you know that the small intestine has three parts, The duodenum, the jejunum and the ileum, Each of them has a special role. They are lined with different linings so they can absorb different nutrients. The first part is the duodenum which has two tubes entering from the pancreas and liver, which secrete chemicals important for digestion. The second part is the jejunum, it is the middle part it's job is to absorb nutrients like proteins, fats and cholesterol. The third part is the ileum, it's job is also to absorb nutrients but it also connects rectum which is the end of the small intestine. Some of me is sent to the large intestine for water to be drained.
This has been a long journey but it seems like it's coming to an end. I have travelled down into the rectum. Where I am stored temporarily. I am now in many parts and look nothing like a cheese and ham sandwich, the human has now gone to the toilet and I am exiting the anus and flushed down the toilet.
