Digestive System

  1. 1. Objectives<br />Enumerate the different organs in the digestive system, <br />Give the contributions of each organ in the digestion process, and<br />Trace the food pathway in the digestive system.<br />
  2. 2. Song<br />http://www.youtube.com/watch?v=pZEzv-hXQRw&NR=1<br />
  3. 3. Guide Questions:<br />1. Describe the path of food in the digestive system?<br />2. What happen to the food as it goes to the following organs:<br />Mouth<br />Esophagus<br />Stomach<br />Small Intestine<br />Large Intestine<br />3. What are the digestive organs that the food didn’t pass through?<br />
  4. 4. Video<br />http://www.youtube.com/watch?v=Z7xKYNz9AS0&feature=player_detailpage<br />
  5. 5. Parts of Digestive System<br />
  6. 6. Mouth<br />It breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.<br />
  7. 7. Esophagus<br />Transport the food from the mouth to the stomach<br />
  8. 8. Stomach<br />The stomach acts as a storage bag of food. The stomach contains three layers of smooth muscles which also produce peristaltic movements to continue breaking down the food<br />
  9. 9. Small Intestine<br />The small intestine is about 2.5 centimeter in diameter and 6 meters long. The work of the small intestines is to digest food, which can then be absorbed by the blood.<br />
  10. 10. Large Intestine<br />The large intestines is about 5 centimeters in diameter and about 1.8 meters long. The work of the large intestine is to absorb water from the undigested food, hold the undigested food for a while and then excrete it as feces. <br />
  11. 11. Accessory Parts of the Digestive System<br />
  12. 12. Liver<br />It produces bile, a substance that helps in the digestion of fats.<br />It stores glycogen, vitamins and some minerals, such as iron and copper, which are released when needed by the body.<br />
  13. 13. Gall Bladder<br />Bile produced by the liver passes through a small tube and is stored in the gall bladder. From the gall bladder, bile is released to the small intestine digestion. <br />
  14. 14. Pancreas<br />Its function related to digestion is to produce pancreatic juice. Pancreatic juice helps in neutralizing or weakening the acid in food inside the stomach before it moves onto the small intestine. <br />
