  14. 14. How to make your stomach better <ul><li>The only ‘cure’ for celiac disease is to stop eating gluten. </li></ul><ul><li>But, I still want to know how the gluten made me feel so sick? </li></ul>Sourced from: Power Point clip art
  15. 15. Where does food go when it is eaten? <ul><li>Food is chewed in the mouth. </li></ul><ul><li>Moves down the esophagus. </li></ul><ul><li>Enters the stomach. </li></ul><ul><li>Food then enters the small intestines. </li></ul><ul><li>This is where the body takes important nutrients from the food we eat to make us healthy. </li></ul><ul><li>Inside the small intestines are small finger like projections called villi, that help take the nutrients out of the food. </li></ul>Sourced from: www. commons.wikimedia.org
  16. 16. What do ‘villi’ look like? <ul><li>This is a picture of what villi should look like in a healthy person. </li></ul><ul><li>These finger like projections are flattened in the small intestines of someone with celiac disease who is eating gluten. </li></ul><ul><li>This ‘flattening’ is irritating and causes pain and bloating. </li></ul>Soured from: www.nutriplexformulas.com
  17. 17. Why was I feeling tired? <ul><li>The villi provide a larger surface area inside the small intestines. </li></ul><ul><li>When they are flattened, there is less surface area. </li></ul><ul><li>The greater the surface area, the more nutrients can be taken into the body. </li></ul><ul><li>The smaller the surface area, the less nutrients are taken into the body. </li></ul><ul><li>Without all our necessary nutrients, our body becomes weaker and tired. </li></ul>Sourced from: www.clusterflock.org/2006/03/daily-calorie
  18. 18. Surface Area <ul><li>The first cloth represents the small intestines with healthy villi </li></ul><ul><li>The second cloth represents the small intestines which have the villi ‘flattened’ due to celiac disease </li></ul><ul><li>Let’s see which one soaked up more water (i.e. nutrients) </li></ul>
  19. 19. Which surface area soaked up more water? <ul><li>The first cloth (with ‘villi’) soaked up much more water. </li></ul><ul><li>This shows that the villi help to create a larger surface area inside the small intestines, therefore, more nutrients are able to be soaked up. </li></ul><ul><li>When the villi are flattened, much less nutrients are soaked up (see 2 nd picture) </li></ul><ul><li>This is why someone with celiac disease feels weak and tired, because they are not taking enough good nutrients from their food into their body to nourish them. </li></ul>
  20. 20. Good things in, bad things out <ul><li>The inside walls of our small intestines (including the villi) have the ability to allow the good things into our body (nutrients), and keep the bad things out (toxins). </li></ul><ul><li>How does it do this? </li></ul><ul><li>Look at the next three pages for some possible examples to help us understand… </li></ul>Sourced from: www.juliahavey.typepad.com & www.candidablog.com
  21. 21. Closed door? <ul><li>A closed door will keep everything out… </li></ul>Sourced from: www.stillseraphic.blogspot.com
  22. 22. Open window? <ul><li>An open window will let everything inside… </li></ul>Sourced from: www.picturepost.wordpress.com
  23. 23. Tea strainer? <ul><li>What is the purpose of a tea strainer? </li></ul><ul><li>It allows the tea in for us to drink - </li></ul><ul><li>But, it blocks the tea leaves from entering the cup. </li></ul><ul><li>So, it allows the good things in (tea), and keeps the bad things out (tea leaves). </li></ul>
  24. 24. Semi-permeable <ul><li>The tiny holes in the tea strainer are just big enough for the liquid tea to go through, but they are too small for the tea leaves to go through into the cup. </li></ul><ul><li>Similarly, the inside of our small intestines have tiny spaces that are just big enough for the good nutrients to pass through, but they are too small to allow the bad toxins into our body. </li></ul><ul><li>A wall like this is called: ‘ semi-permeable ’. </li></ul>Sourced from: Power Point clip art
  25. 25. What have we learnt? <ul><li>Our small intestines are lined with ‘villi’, which are ‘semi-permiable’ – to allow good nutrients into our body, and keep the bad toxins out. </li></ul><ul><li>Celiac disease causes the ‘villi’ to be flattened when gluten is eaten. This reduces the amount of surface area needed to soak-up all the good nutrients. </li></ul><ul><li>This causes pain and bloating to the stomach, and makes the body feel tired and weak. </li></ul><ul><li>However, when the person stops eating gluten, the villi heal and grow back – therefore the small intestines are able to soak up all the needed nutrients and the body’s energy and strength are renewed. </li></ul><ul><li>Try this last quiz to see what you have learnt… </li></ul>Sourced from: Power Point clip art

  27. 27. Quiz <ul><li>What purpose do the villi have inside the small intestines? </li></ul><ul><li>Provide greater surface area….click here for A </li></ul><ul><li>Slow down the digesting food….click here for B </li></ul><ul><li>Help to keep the digesting food moving… </li></ul><ul><li>……… ..click here for C </li></ul>Soured from: www.nutriplexformulas.com
  28. 28. Quiz <ul><li>When the villi are flattened in the small intestines of a person with celiac disease (eating gluten), why do they feel weak and tired? </li></ul><ul><li>They have to work harder to grow back? </li></ul><ul><li>………………………………………… .…….click here for A </li></ul><ul><li>The surface area is reduced, therefore the needed nutrients from food are not all being taken into the body…………………………………..……click here for B </li></ul><ul><li>The digesting food passes too quickly through the small intestines, not allowing enough time for all the necessary nutrients to be taken into the body………… </li></ul><ul><li>……………………………………………… click here for C </li></ul>
