Task- The Journey of a Ham and Cheese Sandwich
Hi, I am a Cheese and Ham sandwich. I have just been made and I am crispy and hot, I am siting on a plate, I am not sure what I am meant to do but it looks like the human does. Before I can even think about it I have been grabbed and heading towards the humans mouth. "Oh no I am getting eaten". Digestion has began, I am now getting chewed and mushed by big white teeth, I am also getting covered in Silvia it's clear and very gooey the enzymes are attacking breaking down starches, the big red tongue is rolling me around getting me ready to be swallowed, this is called physical digestion.
Now I am in tiny pieces and falling down the oesophagus, it is very muscly and it pushes me down by contracting behind me and the muscles relax at the front. This process is called peristalsis. When food or liquids are swallowed a flap called the epiglottis flops down over the windpipe to make sure the food enters down the right way.
Suddenly without warning I am getting coughed up, this is clearing the windpipe. This happened because the epiglottis didn't have enough time to flop down.
After I have recovered I am pushed down to the stomach, the stomach is a very cool place, it stores food for 1-6 hours but during this time it churns the food into a chyme, partially digests protein and absorbs water, the stomached is lined with a layer of mucus which prevents the digestive juices from damaging the walls of the stomach, the juices also contain hydrochloric acid which kills bacteria and microorganisms. I can also see something else! The liver is the body’s largest gland, It sits to the right of the stomach where it not only detoxifies the blood, but also aids in digestion by creating bile, which helps break down fats. Bile’s salts break up fat into smaller pieces so it can be absorbed more easily in the small intestine. Enzymes are everywhere there speeding up chemical reactions and
