- I start to chew with my mouth and swallow
- Digestion is a process of how food is broken down, so that it can be absorbed by the body.
- The three food groups in a cheese sandwich are: Carbohydrates (this is found in the bread and gives us energy). Proteins (this is found in the cheese and helps us grow) and Fats or lipases (these are found in the cheese and butter, they are needed for energy).
- The pancreas and the liver all contain enzymes that help to break down the food as it travels through the body
- The saliva in the mouth starts to break down the sandwich so it is easier to be swallowed, as the saliva contains theCarbohydrase enzyme. Once I swallow it travels down the oesophagus into my stomach.
- Broken down food travels firstly to the small intestine and then onto the large intestine
- My stomach makesHydrochloric acid and kills bacteria. My body absorbs all protein and moves the food down into my small intestine
- How long is this going to take? maybe I should have had one of those 'Get Going' bars instead!
- My liver creates bile to help break up fats in the body and my pancreas makes 3 other enzymes, protease which digests proteins, carbohydrase which digests carbohydrates and lipasewhich digests lipids/fats. All of these processes help get nutrients into my body as they break down my sandwich.
- isMy broken down sandwich is digested and absorbed into the bloodthroughthe smallintestine and then sent through the large intestine where it absorbs water and then is compacted into poo!
- This is the end of my cheese sandwiches journey!
