  1. The Journey of a cheese sandwich!

  2. The Mouth • The Mouth is the first stage of the journey for the Cheese sandwich. Once in the mouth the cheese sandwich gets broken down by your teeth. Your molars start grinding the Cheese sandwich down, the Cheese sandwich is also broken down by enzymes. Enzymes attack the starch. Your saliva coats the food and makes it easier to swallow.

  3. The Oesophagus and Stomach • Once the food has been chewed and swallowed it will go down the Oesophagus which will take it to your stomach. Once in the stomach it will stay there for 2-3 hours while being churned around and turned into chyme.

  4. The small intestine • Once the chyme exits the stomach it goes into the Small Intestine. In the small intestine the chyme gets broken down even more. The food now has tiny molecules in it. These molecules are small enough to pass through the walls of the small intestine and into the blood stream. The Blood Stream

  5. Assistance • When moving along the intestines the food gets a little assistance from the muscles lining the walls of the intestines. The muscles contract and then retract pushing the food along.

  6. The End of the Journey • If any food is not useful to the body it won’t be absorbed. Instead it will go into the large intestines where any insoluble fibre ends up. • As the Food travels along the Large Intestine, water is absorbed back into the body. Finally the waste is released through the Anus when you go to the loo.

  7. The food groups In a cheese sandwich. • The food groups in a cheese sandwich include starch and milk and dairy. It also contains Protein and Carbohydrates. The Bread is the starch And the butter and cheese is the milk and dairy.

  8. Why does the body need food? • The body needs food to get energy so it can do exercise and things that use up energy for longer. Carbohydrates give you energy of a long period of time while Glucose (sugar) gives you a short burst of energy.
